Wifi is weaker, but then again 3g data is much better compared to N900. It is also a lot faster in connection handshake and getting ip address.

Rotate thing seems to work with some applications in task screen with landscape hack, but the browser is stubborn and always turns portrait.

My browser remembers for instance password to TMO, but fails on the sites where N900 failed too.

My biggest usability gripe currently is the lack of one hand zooming in browser. Double click is too often registered by links, and hidden left border middle click zooms too close. Should be an option to have volume keys for zooming in browser as it was in N900.
