A) Don't don't provide a UK plug, but they any power lead with a Mickey-Mouse shaped end will fit into the Brick end of their adaptor, so that's not a problem!
B) They use a traditional BIOS, not UEFI
C) They see no reason why I couldn't install Windows 7 on the system in dual-boot and they provide instructions to do so.
Sounds perfect for what I'm after, and the laptops are relatively cheap for a very good specification!
I might just buy one - of course, will need to investigate the Customs/VAT issues in hopes that they don't significantly up the price. I do hate tax...
