the desire is the only htc phone I've ahd, so can't compare.
I saw the review which listed desire as no. 1 phone too, was prob what swayed me in the nd - I couldn' find a decent, (impartial) reviewof the X10...
Previous phone was a Sony C905, which was an absolutely fabulous camera, but not great a sa phone. lots I disliked about the phone features, hence why I was tempted away forkm Sony this time.
I was still torn because the Sony X10 camera undoubtedly better than the htc.
htc camera is ok - a bit too easy tojostle and get a fuzzy picture I am finding, but will prob be ok in the long run. I understand this is a big stepup from previoushtc cameras, so if camera isimportant to you, I'd go for the SOny -= hard otbeat as a camera phone, I'd warrant.
I played with the Sonyin the shop. Other htings that put me off:
size: a bit bigger than the desire, although less wide, but I thought would irritate ina pocket.
shape: very square corners - also thought would irritatein a pocket.
was a good screen resolutoin though, and overall a shame I couldn't find a decent review of it before I needed to upgrade, otherwise I think it would've been a stronger contender.
dh is at my phone, so will prob sign up to a smart phonedeal soon too - if so he will get the X10 and we can swap around as necessary (have heard that the batterylife on the X10 not great, but tbh I'm not findingit brilliant on the htc either!)
