I thought the OEM was identical to the Retail with some licensing limitations? Since I only have one computer (a laptop) I can save a lot of cash by purchasing the OEM vs the Retail version of Home Professional. I don't care about no support from MS theres plenty of support available through the Forums. I also have no issue with limited licensing either. The savings more than outweigh the limitations of buying OEM. I hope my thinking isn't flawed here. At any rate my budget won't allow me to purchase the OEM version this month so I'm pleased that MS has allowed us to use the RC until March.
Who knows maybe I'll win some cash at the weekly Gold Dust West Casino drawing this Saturday.
