I've only used Powertracks since I started this stuff. While I upgraded to PT2010 - I'm still running PT12.
As for the GUI - I use the Classic Tracks window and seldom the Piano Roll or the Keyboard. I like it simple.
If I want to add RTs I load my SEQ into RB, do the generation and take it back to PT to edit as required.
Oh yeh - I get along fine with XP-SP3 and 512 RAM and a 2.4.
KISS is a great philosophy if you're a hobbyist. I think PT is a great DAW. Childish looking??? Never thought of it at all. What does it matter . . . it works great. The prettier something looks, the more they charge you for it - you get ripped off for a pretty face which may not have much more substance.

Cheers - Ian
