If it was an N900 (including keyb, same old screen,, FM Tx, removable battery, distinguishable design etc..., you know,.. the lot)

Dual core something
Dedicated GPU
1GB RAM at least
IR receiver to copy remote controls
Clearview camera + HDMI out (the only thing desirable in all those other models)
Maemo 5
Open drivers in trade for the usual no support from Nokia.

for existing N900 loyalists a reduced price backplane upgrade kit will do.

Yes every 2 years the successor swaps between candybar design phone to real men's tool and back - deal?
