Anyone pre-ordered their copy?

I was looking at the differences between Home Premium (about £65) and Professional (about £150!!) and Ultimate (£160).

Home Premium sounds fine unless you want to join a domain, use encrypted external storage file system or use XP mode (I'd just dual boot).

Can't warrant the extra expense of the Professional or Ultimate version.

I'm REALLY tempted to pre-order home premium. £65 for a full retail version (which can be re-installed on any PC rather than single license per motherboard OEM) is a pretty good deal that beats any offers over in the USA.

Really tempted. Anyone taken the plunge?
