I installed Windows 7 in a dual boot configuration with Vista and it installed quickly. Bible Analyzer works flawlessly on 7. It took the same setup routine as Vista so I didn't have to make any changes.
I see some advantages to 7 already. It has a cleaner interface, doesn't pester as much with User Account Control (I turn it off, anyway), and has some more intuitive features. At first glance, I like it better than Vista, even though it looks a behaves a lot like Vista. I don't know how ot is for backward compatibility, though. When it is released it is supposed to have an XP compatibility mode so it will run any software that will run on XP. Still checking it out when I get time.
