In the N900 series, I’d like to see the following:

* At least 1 FULL-SIZED SD card slot
* The same screen as the N810 (daylight-readable)
* The same (hardware) specs as the N800 (decent processor, memory, 2GB of flash is nice but not needed with an SD card slot).
* A rotating camera, with better quality (at least 3.0MP)
* USB-OTG support
* USB CHARGING: This is one thing that could make or break a sale for someone like me, who is usually near a computer, but not always near an outlet. For those whom are the opposite, a 120v to USB adapter could be included (I have a few).
* WiMax and a keyboard is not necessary, especially if it adds to the cost and thickness. Some people may want WiMax, but $50/month isn’t what I’d consider “affordable”.
* Maybe taking some inspiration from the Asus EEE would be nice, i.e. a color pallete that would give you some choice, or different hardware specs for a few different models.

I can’t really think of anything, but a price point of… between $200 and $350?

That would probably work.
