if you're looking at this you probably already know how awesome it is, if not here's some links to check outhttp://www.htc.com/www/product/desirez/overview.htmlhttp://www.youtube.com/watch?v=KUeW6-HTtSU
Qualcomm MSM7230 (new generation of Snapdragon Processor, very fast with awesome Graphics Processor)
Fast Boot (this phone will turn on in about 10 seconds)
With Locations, explore maps with zero wait, zero dead spots, and zero data roaming fees (TomTom maps pre-loaded, turn by turn an optional extra)
There's £3.50 Quidco/TCB available too.
