I had to venture over to another ROM. I LOVE MIUI, but I couldn't deal with some of the sluggish-ness with it. I had some slight issues with it that were posted in the Issue Tracker, but it started lagging on me and I was missing calls/texts. I cleared cache, tried uninstalling apps to free up some space (didn't use an appkiller because I don't believe in them), and the like. It's a great ROM, I just can't use it for the time being until I can get my phone to not lag so much. I use my phone heavily due to being a college student and having two jobs, so my battery isn't the greatest (in general, not ROM specific) and I rely on Gmail, Calendar, Texting, Voice, Email, and Tweetdeck. All in all it just got a little laggy. It may have been that I needed to re-flash, but I figured I'd stick with something more stock until I can stabilize my droid with MIUI. I will continue to stick around though and watch the progress grow.
Me too. Also, I ended up "upgrading" to a Droid 2 so no more MIUI for me. I'm half tempted to switch to an X but I don't know if I can deal with the size. I guess I could get the X and switch between the D1 and X depending on what shirt I'm wearing...
FWIW the D2 doesn't seem much faster than the D1 so it really isn't much of an upgrade.
