I ordered me a Dell XPS M1330. After much consideration, I decided not to wait for OS X Leopard and just get me the latest and greatest Vista. Ultimate no less.
So it can support downloading the English pack and switching everything to English. I also customized it to come with an English keyboard so it’s consistent with the keyboard I use at the office.
I have to wait four weeks (!) before the dang notebook arrives. It appears they are having production issues blamed at the complexity in painting their notebooks crimson red.
