32 or 64 bit, what’s your preference?

I was assuming, though assumption is a dangerous thing, with the launch of Windows 7 most people would still opt for the 32 bit version of the OS, or buy a PC pre-installed with it.  However I’ve been downloading copies of both 64 and 32 bit versions of the RTM release today and while the 64 bit version downloaded within a couple of hours, the 32 bit version looks as though it’ll take days.

Is this telling?  What’s your preference for the OS?
