Let the hive mind of Engadget get that for you.
"I'm in the market for a new phone and money isn't a limitation. I'm also not partial to any particular US carrier, but here are some of the features I'd like to have: WiFi, GPS, good coverage in lots of places, push Gmail (a must!), physical keyboard (a must!), a touchscreen, decent battery life and a relatively slim body. And please, nothing that has a fruit logo on it. No offense to the fruit fans, though. Thanks!"
My stepfather was here in the US a few weeks ago and was enormously surprised to hear there was no real PAYG Internet access, so he couldn't just buy a 3G data card, pump money into a SIM, and use the Internet as he wished in the same way as, apparently, is common in the UK.
I wonder what it'd take for the major US 3G operators to actually get their heads around the concept? Or is it going to be LTE that gives everyone the final push, with economies of scale (everyone standardized around LTE) and an open architecture with SIM card support making the technology as ubiquitous as Wifi and any operator not making every effort to grab customers shooting themselves in the foot.
