Guys, yeah I know it may be for interest only for some of you, and this is how I will take my decision to buy the higher priced one, 2.4 GHz. I've only owned Windows PC until now, so its time to get a Macbook. The fact is that, if I can install Windows on it ( I know I can!), and If I can install any program on Windows I can install on my Lenovo, than it will worth the money for a long run and I will invest the extra £200 to buy it. I'm also considering all aspects, to be able to use a windows mouse with it and continue my work. The only reason I want a new PC / MAC , is that my laptop, although its been wonderful until now, it doesnt have a glossy screen, and my eyes hate it. Who knows if I will ever sell it! The "backlit" keyboard caught my eyes. Imagine.. in the night.. silence.. working on my bed under the duvet! I've been waiting long for this Mac, and I'll get it for student discount! - I will use Mac system for Internet, music, entertainment - I spend lots of time on computer, at work, school, I install many programs and also do web development so I'll need Windows for some time. - The price is high enough for both of the Macbooks, so the price difference doesnt matter this time. Waiting a couple of opinions if the higher priced Mac will make a good replacement for my PC.
