I am a heavy daily user of N900, mainly using it as a "ssh" client to admin my linux server. I am searching for a dream linux device and if you know any existing or soon to launch product , please tell me!

. >= 4' screen
. can type 'ESC', ~, | , <, >, `,^
. preferably same or near form factor of N900
. phone call support is not necessary
. Must support linux like Maemo, Android is not suitable. SSH experience on android and symbian device (like E7) is too painful.
. UMPC /MID like machine on the market is too large for me, and they generally use GMA 500 which is rather cumbersome to adjust screen brightness.
