Hello, everyone. I know there are numerous threads already about whether to get a MBA or MBP. Naturally, it seems to come down to the user's needs, so I was hoping to get some input for my particular situation. We currently have a 2006 vintage iMac (17" monitor, 3GB RAM, 2Ghz processor), which is my primary computer, and a 17"MBP from 2010 that my wife uses. We've decided we want to replace the iMac. I'm torn between a 15" MBP and a 13" MBA. Here's all the relevant information I can think of: Cost: The price difference between the two isn't really a big deal. Less important than getting the right machine. Processing needs: My work mostly just involves using FireFox with 6-8 tabs open. I also use MS Excel often and MS Word on occasion. That's about it. So my understanding is that either computer should be plenty in terms of processing power. Portability: I work from home, so it's not as if I'll be hauling the computer around between home and the office everyday. Still, we do travel every once in a while, and having one lighter computer would be nice for that Usability: a)When at home, I'm working at a desk 99% of the time. So how the computer feels in my lap isn't an issue. b)I'm used to a 17" monitor and am a bit concerned how I'll do with a 13" monitor. (That said, prior to this iMac, I used an old white Macbook, which I measured as having a 12" monitor. So perhaps I'll just get used to it.) Other tech spec preferences: Not much here really. Because we have the 17" MBP, I won't need an optical drive. And the 128gb of storage on the MBA will be plenty for my needs. Summary: I like the idea of a super-portable computer. And I like how speedy the MBA feels at the mac store for simple browsing stuff (which is most of my work). But I'm concerned about the 13" monitor for a primary-use machine. Any input would be appreciated.
