I've recently been thinking about upgrading the operating system on my desktop computer at home. More specifically, I've been tossing around the idea of upgrading to the 64-bit variant of Windows 7. Windows XP has been a decent operating system, but it's definitely feeling its age. Seeing as Windows 7 is being targeted for release on October 22, which is now less than 3 months away, I figured now is a good time to think about how I would upgrade.

Moving to a 64-bit OS would allow me to expand the amount of installed memory in my system. At a minimum, I would go to 4 GB installed, especially since Microsoft recommends at least 2 GB for the 64-bit flavor. To be safe, I think I might also buy some new hard drives and install the OS on those (keeping my current setup intact).

At $199 (for the full Home Premium version; $119 for an upgrade, which I have yet to read about), it seems quite an investment. Has anyone else thought about upgrading to Windows 7? Or is anyone currently running a 64-bit OS? If so, what are your thoughts?
