There are many questions on the forum about whether the MBA is the right choice for them. I share my personal experience - hopefully it's useful for somebody. Old config: MBP 13, i5 late 2011 with 16GB/320GB. As this was my first Mac, I had VMWare with XP active most of the time. New config since 6 months: MBA 13, 2013 model, base model, 4GB/128GB. Forced myself not to use XP anymore. My location didn't allow me to have a 8GB (nor the 256GB) model. My profile: Mobile worker, full time web development, casual usage of Photoshop, Illustrator and Flash. Used the XP environment because I was used to it: Notepad ++ and WAMP. I maxed out the memory to 16GB just because it seemed too cheap not to do it. My concerns: 1) Is 4GB enough? 2) Is 128GB enough? My verdict: I switched my development environment to Sublime Text 2 and MAMP Pro. It was quite a shock, but after a couple of weeks I wouldn't go back. I'm using Alfred to switch quickly between Sublime and Firefox. For larger files and timemachine I have a couple of external WD Passport USB 3.0. Fast! The switch from HD to SSD is incredible. Fast! The 128GB makes me more secure in what I have on my internal disk. Most of the time I have less than 20GB free disk space but it never was a huge issue. The switch from 16GB to 4GB didn't seem to have slowed down my system. I don't use my VMWare anymore - this is obviously a huge thing. VMWare obviously also affects the battery life. I went from 2 hours to 8-10 hours. Many times I leave my charger at home (or I leave it in my car just for emergencies) Overall system speed feels a huge lot faster. I've been working on a retina machine for a couple days. It's more beautiful but for web development it is not necessary. Honestly, if Apple releases a rMBA, I would still go for a normal MBA when I renew my machine. Battery life is more important for me. I type a lot. A huge lot. In the beginning I felt that the MBA keyboard was of less quality compared with the MBP. After a couple of weeks this problem faded away though. Sometimes I ask myself the question: would I switch to a 8GB or a 256GB machine? Yes of course, in my life I always wanted to have the best and newest equipment. But then again, no, this base model really does everything I can wish for.
