My problem is, I don't know with which device I should draw the line in the sand...

Palm Pre is very slow from what I saw in the videos. But maybe IS an alternative. But I don't know if you can use BT for file transfers and the 8GB limit is...

iPhone It is a good phone. I had one, but you can only use it with a jailbreak. Otherwise you are fenced into a cage... a nice one but still a cage.

Motorola Droid Android is maybe a good operating system, but I had a HTC G1 an well... it will never have Android 2.0 or 1.6 so why did I bought this thing when it is outdated in 6 months?!

HTC HD2 Looks good, but well... I don't like Windows Mobile. And if you look at the cpu clock... it is crazy what power you need for running this operating system smoothly and well... I remember the batteries in HTC Touch Pro, G1 and HD... forget them

So only device left is the N900 and the waiting for it...
