I was wondering if I could get a few seasoned MacBook lovers opinions on what would be best for me. I'm looking to buy a MacBook in the next few hours but am a bit unsure as to what to do yet. I was looking at both the MBP 13" and the MBA 13". I don't intend to carry a lot of music or movies around, as I use Spotify and have a 1TB external drive for my movies. I work at a startup doing web development (both front and backend) and use Photoshop CS6 for design. I'm looking for a Macbook that I can take to work, take to meetups, and not face massive performance issues with. I'm currently using a Pentium 4 powered computer at work so as long as it's not as slow as that ;D I also play a few Steam games (basically VALVe's collection) - would be nice to be able to play those. Finally, I may be developing some iOS apps in the somewhat near future. My budget is around £850/£900. Thoughts?
