I have 2008 MacBook Pro and I still LOVE it. It’s faster than most of my friends new laptop PC’s and is a lot nicer looking. Still! It’s a very durable product. The amount of money I spent on it turns out to be the same as they would because they have bought 2 computers in the same time from Viruses or crashes or it just broke.
It’s soooo worth it. I have had no stability problems, I mainly install UI changing jailbreaks like Auxo and Atom. It does void warranty but a jailbroken iPhone 5 is the ultimate phone. It’s the hardware from Apple and some of the flexibility from Android
