Used it on my Touch Pro first, then on my Treo Pro (yikes!), and now on my TP2 since day one. No issues what so ever that I'm aware of, and I have to say it's never looked better than it does on the TP2!!!
Here's a look at my Lifestyle pages...

Oh, and you can actually edit the layouts for separate portrait versus landscape layouts. Now, you can't add different icons to each i.e. they must be the same set of icons / widgets, but you get to rearrange them for one mode versus the other. Nice touch that I didn't realize was available and threw me at first when I switched from my nicely laid out portrait view and it got messed up in landscape....hence why you get to rearrange for both modes.
And if I can add one more thing. The
Professional Widgets by jgjackson make MS3 a truly customizable and productive tool for me.
