Awesome, awesome program. To be honest, I was never waiting for 3.0 since after looking at all the graphics and animations, I was sure it would hog my 200 Mhz/48MB device. I even gave 3.0.0 a miss, since I was sure there were bound to be some annoying bugs. Fact is, this baby runs like a dream on my low end machine, so for all you guys worried about performance - unless you're using a worser device than mine, you don't have to worry about it! MS3 is actually using 2.8 MB RAM - yes, 2.8 MB! I didn't check it by reading the reported memory usage, but be comparing the free memory I had before and after loading MS3. I'm still left with 20+ MB RAM which is plenty for light multi-tasking or for a heavy Opera 9 session.
Battery life is good, haven't noticed any unusual drain so far. I'm quite surprised how, even on a low end machine, the interface is so smooth and flexible. Other implementations like Touch Shell, Wisbar Advance are such a memory/CPU hog, I still can't believe how MS3 manages it while still making it look so good!
Definately worth buying.
