I work at a cellular company, We had a 2 months competition...
I think that i will go over the G2 just because i will have insurance over it,compared to the one.
On the one i have two years international warranty and i have to send the device to htc uk to get it fixed and its takes around 10 days. and it's no including damanges,or if it's get lost/stolen, etc
Regarding the low space on the g2 (8GB that you can use) , i found this pretty useful

Few more words about the htc.
It's an incredible device - i love the sense,boomsound,speed, and overall use. But one thing that i must to say -
htc should offer a housing replacment service for whose intrested!
I own the silver edition. The blue version is exclusively to bestbuy(US) and that's the most beautiful phone i have ever seen.(theres also vivid blue which is exclusively to carphonewarehouse UK)
Even if i choose to stick with the htc, there's nobody that can make that switch (not gonna do it by myself otherwise it would be bricked)
