I have had numerous Apple products, including several MB Airs, iPhones, iMac etc. However the rMB is the worst Apple product I have ever owned. - Sluggish (1.2 - 512) - Horrible battery capacity. Often as little as 4 hrs (Cocunut battery shows it is down to 84% capacity after 100 cycles) - Dongles for everything - Draining power while in sleep mode - Track pad not working well - Does not work with Thunderbolt display - Drops 5gHZ connection on Airport Extreme My user experience was reminiscent of a crappy Asus laptop I had years ago. Perhaps I got a lemon...but it was not good... Bought a MB Pro 13" and happy to drag the extra weight around for something that actually works like a decent notebook.
