capacitive touchscreen is not an issue as the n900 has the best resisitive screen out there.

there are other devices out there, but none quite match the n900 still. it is still a good device and if you can find one second hand or new discounted it would be a good buy.

there is a strong possibility that the N900 sucessor will be announced at the end of next week. even if it is it will probably not hit the shelves for at least a couple of months.

the n900 is still a unique device and will be a relevant device which will be well supported by the community for a long time to come.
