I use tmobile and their plans without contracts are a lot more expensive than the ones with contract. I'd rather buy an unlocked phone and do the month to month thing.
My e63 wasn't compatible with tmobile's 3g. Web browsing was slow and I couldn't talk and browse at the same time. Imagine paying $700 for an iPhone or $550 for the nexus one and still b going through my e63 ****ery.
The n900 was without a doubt the best option for me.
