When I first got my droid x about three months ago from the start I was not pleased with blurs design and performance, having contacts instead of web on the dock was very irritating, one can acces contacts by selecting dialer then contacts, and now with the quick number find added from the lastest update it even easier to find people, no need for a contacts icon. The second biggest drawback I noticed was the lag/choppy delay while moving between windows on the home screen, after using lpp or adw it is MUCH smoother and VERY noticable so what's with the lag moto? Don't get me started on using live wallpapers like light grid pro with blur..
Using lpp or adw reduces the lag dramatically, its an obviouse speed increase and going from stock blur with lpp or adw to a blurless rom is even more of a speed increase in every aspect, like butter.
For me I personally feel as if the droid x is an amazing phone I wont trade in any time soon, but blur is the bottleneck.
