Sony PS Vita
There's no doubt that smartphones based on platforms like iOS and Android are becoming popular gaming devices, replacing traditional portable gamers like Nintendo's NDS and Sony's PSP.
Now Sony is fighting back with a new version of its portable gaming console: the PlayStation Vita, which will now come with mobile connectivity.
While the PS Vita looks very much like the first PSP, it features a multi-touch. five-inch, organic LED display, and the option to be connected all the time over a 3G network. You'll need a mobile data subscription, but if you are big on online games, this is essential.
Of course, once connected, the PS Vita will also let you browse the internet, access social networks like Facebook, and download other apps, including Skype, from the PlayStation Store.
To run all that, the PS Vita features a super-fast, four-core ARM Cortex-A9 processor, as well as a four-core SGX543MP4+ graphics chip, and comes with 512MB of RAM and 128MB of VRAM.
There are also two cameras, for taking photos and making video calls, as well as a rear touchpad that lets you interact with games with your fingers from the bottom of the device.
One piece of bad news is that the PS Vita introduces yet another memory card format from Sony, so all those old PSP games won't work, although you can now download older games directly online.
The 3G-enabled PS Vita is selling for US$299 (about HK$2,330) in the US.
Pros: new multi-touch screen, fast processor, strong graphics, 3G connectivity
Cons: uses a new memory card that won't work on anything else
