Forget men, I want to marry my MacBook.- Alexandra Potter
To replace it, in 2009 I bought the cheapest MacBook that Apple sold. That worked fine a year and half and then some sort of loose cable developed between the computer to the screen and the screen would slowly fade to white until I wiggled it. Some times it would run fine for a day and other times I couldn't get it to work at all.
After that I tried to live in a "post-PC" era and bought a keyboard for my iPad thinking I could get away with just using my iPad and not having a laptop, but it didn't quite work. It was close. It was so close, but if it can't replace 100% of my needs - than it doesn't make my life better.
What was missing? I've been scanning and I can't scan into my iPad. Trying to "scan" by taking pictures with the iPad camera is just silly. The other thing is that I like to do development. Even though some amount is theoretically possible, once I start digging into building a web app - I just can't get myself to do it on the iPad.
Now I have gorgeous new MacBook Air fully beefed out! Let's get developing!
