The gTablet is fine with 512mb, so not sure if this is much of a problem as people may think, but it is still lame, none the less. No arguement that performance would be better with more though....... Only 512mb?? Really? Seems a silly miss by Moto.
The X 2 is MUCH better off with 2gb, since 8gb device app storage was overkill on the X 1, since most apps push large data files to the sd card anyway. With the X 2. you now have 6gb of media storage, rather than wasted space on the Droid X. It will take a long time to fill up 2gb.
Well, 2gb probably = 1.83gb and the 6gb = 5.5gb (due to format parameters). Still a much better set up than the Droid X 1.
