really liked the touch interface but was never really capable since i was used to the iphone and ipad - the smoothness of the iOS killed it for me. plus it got SOOO HOT all the time and the 5+ hours of battery life it had 6 months ago is now 2.5 even with the 2 batteries it has. now i've got a refurb late 2013 MBPro with the i7, 8gb ram, and 256gb ssd. parallels with win8.1 on it. i've always loved the retina display and mac touchpad. refurb because it was a few hundred cheaper than the same model, new. battery life after 2 cycles is almost a full day at the office unplugged. i don't use mavericks for much (besides imovie and itunes) and the PC side does all my other stuff (outlook, dameware, network file OP. i am really liking how fast it is. i transferred 9GB of data from USB over WIFI to the NAS in 15 minutes. it helps that we have meraki enterprise WAPs but my helix would take awhile to do the same.
