Well, over the weekend, I switched to an Ultimate 11 from an Ultimate 13. I sold my Ultimate 13 on eBay and donated a portion to relief efforts in Japan. When all is said and done, after eBay and PayPal fees, the donation, the tax deduction, and the lower cost of the refurb 11, it worked out almost even. Anyway, I realized I was using far less than half of my 256GB SSD, and I've been eyeing the 11" ever since I saw it in the store (the 13" was an online purchase). I am a bit annoyed that while the "256GB" was really 250GB, the "128GB" is only 120GB (less than half the size), but it is enough for me. So far, the only thing I miss about the 13" is the 900 vertical pixels. Going back to 768 takes a little getting used to, but the portability of the 11" is great. Sure, the SD card slot was nice on the Ultimate 13", but with the 2nd USB port on all the MacBook Airs it isn't quite as necessary. Despite the slower CPU, this still feels like a decent upgrade from my Rev B that I was using as recently as last November, and in retrospect, I'd have gone with this one from Day 1.
