The biggest improvements lie not in the Pre 2's hardware but in its operating system, HP webOS 2.0.As operating systems go, webOS was pretty well regarded among technology enthusiasts and users alike prior to HP's acquisition of Palm. The improvements in the new HP-owned version of webOS 2.0 are welcome although they won't blow your socks off.
The Pre 2 still uses the Card system of old to display applications. If you open an app it'll appear first in full screen mode but if you navigate away to another app, by swiping upwards, it will minimise into a Card.
The multitasking capabilities in HP webOS 2.0 have been greatly improved. The Cards are now live, so if you've got a video or news application running and then minimise it into a Card the content, whether it is a video, game or RSS feed, will continue playing or updating.
These Cards can then be organised into Stacks, so you can keep related apps together. Simply hold down on one app and drag it towards another. Stacks are especially useful if you have lots of open apps, which would otherwise look cluttered and confusing. There's no limit on the number of stacks you can make. You can also change the order in which apps appear in a Stack,so you've always got the most important one at the front of each stack.
You're free to populate the homescreen with as many of these Stacks as you like. There's no limit on how many Stacks or singular applications you can have running at once, although the more Stacks and apps you have running simultaneously, the greater the chance of lag and slowdown. Notifications appear at the bottom of the display and are extremely discreet.
