I have you down as a sane rational person so can I ask for examples?
Screen quality is one of the best. If you're worried about fragility I'd say people breaking them are just not careful of their possessions.
Had iPhones since the 1st Gen, prior to that a huge Nokia, SE and Moto fan, I cannot say I've had any reliability issues myself. A friend had a modem issue, one's had an aerial issue but as with most faults, you'll generally find people only write reviews/posts when they have something wrong - when it's business as usual hardly anyone writes 'nothing to see here'
Connectivity - we talking to 3rd party devices etc? Mass storage use or something?
Not against the HTC stuff, I think it's lovely, not played with the S2 yet, but would just like to hear your justification of the points
