Two days ago I converted my wife's machine. It was a snap and she was up and running in one hour with all her files restored from backup. She does not see much difference, but, noticed that it seems to have better performance. I installed the extra games as she likes to play games when she is bored.
I also found out that Beep Media Player can handle streaming internet music. I have had it running for several days now. I put a skin on it so it looks like XMMS. It tooks a bit of digging to find this out, but, the online groups are a great help.
