It's interesting to look at the chart at the top of the thread and consider the iPhone 3G costs $99 as of today.

And comparing devices in a slightly different bent - is anyone else concerned that releasing an n900 type of device on Tmobile will be a huge detriment? Sure, Nokia doesn't market to the US, but releasing a device on a carrier with such comparatively abysmal 3G coverage compared to ATT isn't going to help things. I went into BestBuy a few days after the G1 was released, and the reps appeared to be trained to warn people about Tmobile's coverage before selling it to them.

All of these devices look great overall, but each with a decidedly annoying wart -

N900 - Tmobile?
iPhone - physical qwerty is nice, many other reasons stated in this thread
Palm Pre - Can't do voice and data at the same time
N97 - super duper expensive, perhaps end of the line for S60
