I've been using the stock launcher since 9/8, with sampling other launchers like Go and Zeam from time-to-time. I had Launcher Pro Plus on my D1 for a long time and really loved it, but I read that LP has not been supported lately, with the Developer promising that he's working on a totally new re-write of the app, and customers pissed that he has gone incommunicado for 6 months.
While I love the stock launcher, I was continually annoyed with the lack of portrait display of the desktop as I often use the Bionic horizontally. So I gave my old standard LP Plus a try. Wow, VERY nice on the Bionic!
I know that Go is a virtual copy of LP, but I like the LP crisp/clean look and when I set the transition and preview speeds to "instant", damn, the Bionic just smokes! Everything is so fast, it's like LP makes better use of the processing power than stock. I've not had a single hiccup with LP since I installed it a couple of days ago, the calendar widget is the best I've found, and the vertical scrolling of the app tray is really usable.
Even though it hasn't been updated in a while, this launcher works great on my Bionic.
