@Jack6428 Assuming you aren't joking, too, I can't let you go on being upset. Qole was joking, in his Canadian way, that you can't plug in a Bluetooth keyboard. You can, however, wirelessly connect a keyboard to the N900 via Bluetooth.
If you don't have an N8x0, you should go and get one. They're pretty cheap right now, and they do a lot of the stuff that the N900 can do. The N800 has two full size SD slots, and a mini USB connector (as opposed to the micro USB connector), not to mention it is probably cheaper on eBay, so it might be better to use as your WiFi USB Host.
