With the speed bump for the Mac Mini, I am looking at getting one, but I have a few questions first:

Can I use (legally) the same copy of Windows XP under both Bootcamp and Parallels?

I assume XP needs activating under Bootcamp but what about in Parallels? If it needs activating twice, will that cause problems? (see above question).

Does OSX Tiger have backup software that will backup to the superdrive?

I will up the RAM to 1GB anyway, but will I see much difference in performance if I max it out to 2GB if I am only web browsing, checking email and using the iLife suite and Office (for Mac) and occasionally ripping CDs/encoding MP3s?

Will the speed difference between the two processors be noticeable given the usage profile above?

Thanks!
