Well you keep saying you bought it due to the iPhone 5 and for web browsing. It's overkill for that. But if you really love Macs and had the money to spare, then more power to you.
Most people, including myself, use Macs for productivity and because we really like OS X.
im finding the Macbook pro more useful everyday and the tech that comes with it im quite fond of hence why im buying the 5s. Its also great for tuning vehicles which makes me love it more.
Trust me I dont have money to spare im actually quite frugal but I may make one or 2 major purchases a year and these were it this year
