Loving this phone I hope this vid helps show how smooth (or laggy lol) the phone is! Sorry not the clearest vid hope I covered enough in this short clip.
Please remember this is the phone straight out of the box, no tweaking. Now think about all the tweaking Rom flashing etc. NECESSARY for WinMo phones. Even with some of the best Roms they were still a bit quirky. Honestly, if this is ground zero I cant wait to see how far Android will go. The phone has a LITTLE lag from time to time and a few small issues that will be addressed in time. ALL new phones have some bugs that have to be worked out its just the price of early adoption
