I really want to switch to Mac. I used Windows PCs in my whole life and I want to try something different. I loved it's design, OS X, it's screen, backlit keyboard, multi touch gestures etc. I don't want 13 inch model beacuse it's screen is too small for me. So I want 15'' model but It's expensive. I can afford it but I am afraid to waste my money. I want to use it for at least 5 years, so will it's battery still be OK to use it without carrying charger to everywhere? Will it able to run apps and programs after 5 years? Is it future proof? I am a regular user, I use my computer for browsing web, checking facebook, playing league of legends sometimes (and it's avabile for OS X). Is it worth it?
