QOTD: Which Version of Windows 7 Do You Use?

It's been a full week since Windows 7 officially hit the mass market. Those of you who pride yourselves in being early adopters of technology have probably already got your Windows 7 machine all tricked out and running better than things were before, be it on Vista or XP.

Microsoft believes that Windows 7 Home Premium will be the overwhelming edition for mainstream computer users, despite how much cooler-sounding Professional and Ultimate (especially Ultimate) are. Much of Home Premium's popularity will come from the fact that it'll be the most popular SKU bundled with new PCs – but you guys who build your own have a choice.
