I have been torn between buying a 15 inch and 17 inch MacBook Pro. My initial theory was to just buy a 17 inch MacBook Pro (seeing that the 15 inch is not significantly cheaper compared to the 17 inch). I was happy with all the 17 inch configurations except that it has no back lit LED display. My question is why? Seeing that it's the top of the line notebook (it even has 3 USB ports and a front load for DVDs), but it "conveniently" does no include backlit LED. Is this such a very precious feature I could do without? Will no backlit LED make the MBP battery more vulnerable to swelling? Also would anyone know if the 17 inch will be upgraded with this feature anytime soon?
