Okay - still playing with it myself - and so far, I have to say, I like! The changes to the default skin make it a lot more appealing to me - and the ability to change the colour of it is great for getting it to match the rest of my desktop.
Fortunately, I didn't run into any of Barry's problems - installation went without a hitch, and it all runs perfectly.
When I saw his comment about CPU useage I got curious and checked - yeah, CPU useage was high - around 40%, but that was with the Alchemy vis (nice vis, IMHO!) running in a fairly large window. Enh - big deal - I set it to no vis and my CPU useage immediately shot down to a -very- respectable 2% - neither Winamp nor WM8 ran that low for me.
All in all - I like!
