For me the question now is "when I'm ready to upgrade which phone software is going to restrict me the least?"

Generally, I don't care too much about the hardware - it's how much freedom will the software allow me?

The n900 is perfect for me because I can write software for it and it's reassuring that the n900 OS is mainly accessable.

Apple's iPhone does not allow you this nor does Windows Mobile 7 (some of its API features are only accessible to "Microsoft Approved Partners" e.g. no ability to change some UI components or it's limited "multi-tasking" features)

There's also the drawback of only allowing you to install apps "approved" by both these companies.

I'll quite happily wait until a Meego device is ready and I don't care if Nokia make it or not. I'll jump to whoever can give me the most flexible product.

Realistically, we are probably talking about a good 9 months or so before a MeeGo phone from Nokia is actually available to customers. There is a possibility another company will beat them to it.

Until things are clearer I'm sticking with my n900 - I'm very happy with it and do not feel the need to buy the next device just because its newer.
