Actually this have been my dilemma since Windows XP. Here's my requirements:
- I live in Japan, and my girlfriend is japanese. So I want Windows to display English UI when I logs in, and display Japanese UI when my girlfriend logs in.
- My office suite is Office 2007 Pro English
- My VS is VS2008 Pro Eng
- I have some hardwares that have only Jap drivers.
- Its preferable if I can get system errors in english. (I have not much problem reading japanese, but still english is easier to understand)
- IME is important

Anyone can give me an advice on which Windows 7 should I buy? (Especially, if I should buy Win 7 Jap or English?)
