Probably not, unless you want BitLocker.im looking at windows 7 professional, is ultimate worth the upgrade?
havn't updated yet, i need to.10.04 (as of April 29th)
i just updated today, support for iphone has been added (woohu!)It is a little apple'y and you will want to download the hack for moving the folder buttons back to the right side (unless you like them on the left), other than that it has been trouble free for me.
