I am a long time PC user about ready to purchase my first Mac - a Macbook Pro actually. I believe that the 15" MBP's are using the LED display now, however I heard via rumor that they will release the Penryn 45nm chips up to 2.8ghz in January. I'd like the opinion of others if this is something worth waiting for or not? I have other computers so this isn't a necessity, however I can get a better corporate discount if I order it soon - I'm weighing the options. Opinions? Thanks in advance!
