I bought a refurbished MacBook a few weeks ago and I love it. Unfortunately, it's the older model with the GMA 950 video, less spacing where the grill is, and the older style function (F) keys. I was wondering if it would be possible for me to buy the newer style F keys, pop the old ones off, and stick on the new ones. After reading a post the other day about some guy breaking his MBP keyboard by taking off his keys, I'm not feeling too good about it. So it's either that or get a new keyboard, and I'd rather not do that because I'd like to keep my warranty. Any thoughts? Thanks!
