"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!"
Hate that they replaced SD with miniSD. SDIO would give the device lots more expansion options. There are SDIO based GPS, SDIO WiFi, and Philips has demoed an SDIO DVB-H mobile TV card. Imagine you can use all these with the GSM based Treo 750.
