Thank god I checked here first. Was planning on going out tonight and buying a mac mini, but then I saw in the buyers guide that there is a rumored upgrade to it...How solid is that "within a few weeks" date, do you think? Is that when they will be starting to upgrade and they won't hit stores until the summer? I am really in the need for a new PC and was hoping to purchase one very soon. http://www.macrumors.com/2008/03/07/penryn-imac-and-mac-mini-updates-soon/ Thanks very much!
