Or, more importantly, you could ask whether Nokia's N900 is the thing to buy.. NOW. For how long will it be supported by Nokia? How is the support now? Try calling Nokia's support line to see how easily they satisfy customers (my unit is damaged, do you cover repairs? How? How long will I be without my device? Will it gets fixed or just replaced? Can I buy a new part? (pick a part--stylus? battery cover? etc.). How open is it, really? Put your paws on competitor's devices so you can compare it to this. Can you even find an N900 to try out?

My opinion? Ultimately, I think you might find that the N900 isn't a particularly good deal anymore. Most people here will disagree because, well.. you're in the Maemo forum. Go ask the Apple or Android people if you should buy one of their devices. Of COURSE the Maemo will be heavily biased.

Thankfully, I've never been a big fan of limiting my scope so I've always been open to looking toward these platforms with a bias towards what works best for myself.
