I swear by by MacBook. Had always been a PC person before I bought it about two years ago. Before that had a Toshiba. It was ok and lasted a few years. Eliminated the "desktop" a few years ago. You can always get a hard drive for storage.
I don't store data on my lap top at this point. It's mostly used as a convenience when I don't wanna sit at a desk. I'll look at a MacBook and see what it's got goin'. Honestly, I've never tested/used Apple's products.
