While browsing the beautiful new Micro Center (Rockville, MD) yesterday, I ran across a pretty sweet deal on Mac OS X Leopard. Assuming you’re not one of the millions who’s already upgraded, Micro Center’s $40 rebate is being offered both in-store and online though 11/11. While Spaces appeals to me, I haven’t really felt the urge to update my MacBook Pro. Though I did re-Vista-fy my Media Center PC last week.
