It's been a long time since Sony Ericsson came out with a significant smartphone that could handle the market. Not the XPERIA Halon, might just be another one of those high-end smartphones in the market.
With 1GHz Scorpion CPU and Adreno 250 GPU, multitasking won't be a problem. In fact they also chunked in 512MB of RAM for your needs.
The screen resolution will be 480 x 854 pixels together with Android 2.3 Gingerbread. Not to forget, the Halon uses Sony Ericsson BRAVIA Mobile engine in its display which I believe will be great for watching videos.
The 8MP camera uses the EXMOR R sensor (technology in most Sony's digital camera) and capable of 720p HD recording.
The Halon will be in the MWC 2011 and it will be worth to check it out.
