Well N900 is a great phone and dont feel its lacking anything really, but im a tech junkie and want to try something new.
Will give the Nokia E7 a try until a proper Meego phone is out.
Want the usb function to cut away my epson backup unit for the camera.
Also want the hdmi for presentations.
Even though S3 is a pretty inferior OS to the maemo one its functional and keeps battery time waaaay better then the N900 based on a pre production unit I had for a few days.
+creen is superb.
But the N900 is a love/hate phone... Mostly love though
