Having so much cellphones with Linux operative system (Android anyway) sliding keyboard and under US$ 200 with much more power than the N900 or even the propossed Neo900 hardware, i believe that spending much more than US$ 300 would be a waste of resources.
I still love my N900 but after fidling with some new phones and having found a more than suitable replacement for US$ 250 that allows me to do everything i did with my Nokia and some new stuff, along with a way better camera and 1080p stable video record...
Sorry guys but is time to move on.
