Unfortunately you'd have to wait til Q3-Q4 for the Xperia, but yeah it looks sweeeeet. (the following is my own personal experience, so your YMMV) I'll admit I've always been somewhat lusting after an iPhone, but was prevented from getting one for a number of reasons stated in this thread (esp the virtual keyboard, plus the fact that I'd have to get a jailbroken once since I don't live in the good ol' US of A) but eventually I caved in. I went from a HP iPAQ 69XX (I forget what model exactly) which imo had the bestest QWERTY keyboard ever, and it only took me a day or two to get used to the keyboard. I was floored by the 'intelligence' of the corrective text input. Sort of like going from regular text input to the T9 dictionary in the old days, but better! Okay, I'll admit that the lack of 3G is going to be a turn-off for most people, but I still haven't made that leap yet since my iPAQ didn't have it so maybe I don't know what I'm missing. I'm somewhat blessed though since where I live, there are wifi hotspots liberally sprinkled all over so I'm more or less covered if I need my wifi fix. And yeah, I could've gone the boring corporate route and gotten myself a blackberry, but I managed to fix it up with the IT guys where I work to set up IMAP on my iPhone and it works great. Hey, it's not push but if there's really something that urgent to respond to someone'll call, right? For regular email the EDGE works fine. I mostly use it to trash emails on my morning commute anyway
Contacts, calendar etc sync with outlook so no problems on that front. I kinda like the iPhone calendar better than the WM6 calendar anyway. I've generally had poor experiences with GPS on cell phones anyway. It's fiddly and takes pretty long to get a fix and all that. If it's that important, get an in-car unit, you'll get much better mileage in the long run. The Google Maps feature on the iPhone works pretty well for what it's meant to do, so I'm happy with that. I don't really use it as a video/music player either. The built-in speaker is pretty impressive, but I have a regular video ipod so I don't really need the iTouch capabilities of the iPhone. The screen is fantastic though. It sorta kinda does attract fingerprints, but it's nothing a wipeover with a soft cloth once in a while can't cure. I mostly keep it in my pants/jacket pocket so it gets 'wiped' over while in there. So, yeah. To cut a long story short, it pretty much works as well as my previous phone did, except it looks *much* sexier. I can't comment on the MotoQ or Curve but what I can say is, underneath all that eye-candy and Apple-ness about it, what you have is a fully functioning phone that pretty much does what it sets out to do.
