The tablet or the laptop?

Mobile devices have had a good run lately. First there was news that more wireless devices are being used in the United States than there are people to use them. Then we learned that accessing the Internet by mobile device doubled in 2011. Now we have the prediction that tablet sales will approach 500 million per year by 2015.

This, of course, is bad news for traditional PCs — desktop and laptop computers alike — that also officially will fall behind tablets in sales by 2015, according to projections from Business Insider Intelligence, an Internet industry research firm.

Alex Cocotas, a BI Intelligence research analyst, went so far as to declare that "the post-PC era has arrived." That's clear at home, where reading a book, checking your email and finding recipes has become a far more fluid activity on a tablet than a PC laptop battery. But how that impacts business travelers — for whom laptops are only slightly less essential than oxygen — is to be seen.

Apple said last year that more than 90 percent of Fortune 500 companies are testing or using iPads and iPhones. But don't expect laptops to disappear any time soon, especially among business travelers, Cocotas said. The following discussion was edited from a longer conversation.

Q: Does the "post-PC era" mean the end of the laptop for business travelers?

A: The main knock on the tablet has been that it is a leisure device, and for business travelers, how useful it is depends on your needs. If you're trying to run programs running a lot of data, ACER LC.BTP03.003 Battery a laptop is still the perfect device. Tablets are great but not suited to that kind of work.

Q: Is the issue simply hard-drive size and the fact that tablets are rarely (if ever) larger than 64 gigabytes? Can they catch up?

A: Tablets don't have as much memory as laptops, but also the number of shortcuts and functional features make using and searching large data sets quicker on laptops. It's tough to say if that will ever come to tablets, but I imagine storage and battery life are two things they're working on APPLE A1185 Battery.

Q: So where will tablets make inroads over laptops among business travelers?

A: We'll see a lot more customized tablets with customized apps, like product or inventory information unique to particular companies. You can really use tablets in any number of ways. That's one of the exciting things about them.

Q: How big is the role of smartphones for business travelers in the "post-PC era?"

A: Huge. People are increasingly using smartphones over computers ASUS A32-F3 Battery. Every business traveler has a smartphone, which most people really use as a mobile email device more than anything. It has become a cliche to see a business traveler walking through the airport, looking at their phones. You certainly see that much more than them looking at laptops in the airport lounge.

How To Extend The Smartphone, Tablet Or Laptop Battery Life

Theoretically, Li-Ion or Li-Po batteries should ensure a permanent working period. However, the charging cycles, the temperature on which these devices are being exposed and the environments in which they are placed, could significantly reduce the energy storage capacity of the batteries. The next advises would help you extend the battery life of your device.

Recharging cycles.
it is always a good idea to never let your battery to drain completely. Once it is drained completely it could appear the risk that the battery to not be able to start the loading process again. The bigger risk is with Li-Po batteries, as described above. Therefore we advise you to recharge your battery when the energy level goes below 20-30%.
Another thing you should is that it doesn’t matter if the battery is fully recharged. You can unplug the recharger even if the level of energy is lower than 100%.
A charging and de-charging process is called cycle. The producer of a battery specifies that this has a life of 300 to 500 cycles. In reality, the the number of these cycles is much higher when you are charging your laptop battery more frequently. The below mentioned table would give a good ideea:

De-charge grade	Number of cycles
100%	500
50%	1500
25%	2500
10%	4700

In the last period of times, the battery producers are measuring the life of these devices in years, but this not a very accurate term.
Storage and Temperature.
the number of cycles is not the only factor which decides the life of your battery. Anther very important issue is the environment and the temperature in which the batteries are being kept.
Therefor, if you are not going to use the smartphone for a long period of time or you plan to use the laptop at home without its battery for a long period of time, then you should load its battery to 40% of its capacity, and to store it at a temperature of maximum 25 degrees Celsius. It can even be stored in the fridge, at a temperature of 2-4 degrees but not in various environments where the temperature goes below 0.
Caution: if you plan to use the laptop at home, plugged in to the power network, then you should know that, if you keep the battery inserted, this one will stay permanently loaded at 100% and at high temperatures, too.
What to expect in the future?
Despite the fact that it does not show, the Li-Ion technology is currently developing and the performance of these kind of batteries are currently growing with 6% each year. However this process is too slow and cannot keep the pace with the fast hardware performance growth.
The things are slowly being improved. At the end of the last year, a researchers team from Lawrence Berkeley National Laboratory (California) has created a polymer device which is able to store 8 times more energy, improving in this way the battery life.
In the same time another team of researchers from Northwestern University have managed to increase by 10 times the storage capacity of a li-Ion capacity. This was accomplished after discovering a way through which the number and the mobility of the ions can be increased.
Bill Gates has also invested in Liquid Metal Battery which is currently developing a battery which is based on liquid metals.
Therefore, even if for a period of time we will have to use the same old Li-Ion and Li-Po batteries, the futures still sounds good.
Conclusions.
The way of using and storing a battery can have a major influence on its life. However, the rules of keeping these device are very simple and can be very easy accomplished.

What students need to know when buying a laptop

Buying a laptop (or a notebook, as some call it) isn’t easy.


Doing so requires determining what your needs actually are because, without that, laptop specs can be a confusing array of numbers that don’t truly paint a proper picture.


Is speed more important to you than hard drive space? Are graphics more integral than the built-in speakers? Is a smaller screen more important than having a CD/DVD/Blu-ray optical drive?


There are low price ACER AS07B31 Battery, ACER AS07B61 Battery with high quality at our australia acer battery online shop.


These questions matter because finding the happy medium isn’t easy, and you almost have to project what it is you will need later on. You want to be able to hammer out papers and essays, but also have the flexibility to edit photos and watch limitless amounts of video.


Unlike desktop computers, laptops have little room for upgrades and tweaks, but that doesn’t mean there isn’t room for improvement. It may surprise you to know that you actually have more leeway in telling the manufacturer what kind of a laptop you actually want. This goes for Macs, too, as Apple offers build-to-order options for its laptops as well. These types of orders are typically done online, where you can choose to upgrade specific components.


This is rarely an option with brick-and-mortar retailers who agree to sell particular specs for the computers they carry. But there is a difference when ordering a laptop through the manufacturers’ websites. So, for example, if you were very happy with all the specs of one particular laptop, but preferred to have more RAM and hard drive space, that can be done, albeit for a bit more money.


We also provide brand new ACER AS09D70 Battery, ACER AS07B41 Battery, ACER AS07A31 Battery with 1 year warranty.


Rather than focus on specific laptops on sale now, we’ve instead focused on what the specs actually mean.


Processors — The lifeblood of a laptop, the processor determines how fast applications and tasks run. If you’re looking to run several apps at once, an Intel Core processor is a much better option than the Atom ones used in netbooks, for example.


RAM — RAM is installed memory, so the more you have, the more apps and tasks you can run simultaneously. Having just 2GB of RAM may be fine for minimal needs, but you’re better off starting with 4GB if you need to multitask more. The good news is that RAM is one of the easiest specs to upgrade.




Hard drive — This is an easy one, because it all depends on how much data and content you feel you need to store on your laptop. If it’s going to be your entertainment hub, then you might want to get more to be on the safe side.


Screen size and weight — The bigger the screen size, the greater the weight of the laptop. For example, it’s hard to find a 15-inch laptop that weighs less than five pounds. It also depends on if you want a glossy or matte screen.


Laptop Battery life — Never trust the number you see on a spec list. Battery life is so relative that the number quoted is not based on actual usage patterns. So, if you see “seven hours”, the more likely number is five.
