I've had a Droid X for about five months now, and love it. However, since I had an upgrade coming, I thought that I would try the R2D2 version of the Droid 2 as a second line. Gee! I love this one too. There are noticeable differences, but not the type of differences that are negative. For example, I can wake up my Droid X by tapping on the home key as well as the power key. On the Droid 2, only the power key will wake it up. Talking about the power key, the placements are different, and if my mind is on something else, I find myself trying the center of the top of the Droid 2. Neither of these differences are bad. Screen sizes are obviously different as is the camera pixels, but the differences are not, at least to me, that noticeable. As far as performance, they are equal. Actually, I believe that the Droid 2 is a bit faster in downloading. To sum up, I really enjoy using both cell phones, and find that any differences between them are not negative. How do I advise anyone asking me which one to get? That will be a tough one. Screen size, camera pixel?
