I owned the MBA 1.0 and ended up returning it to Amazon after I just couldn't justify the cost of the machine when it was so slow for some tasks. 1) How warm does the MBA 2.0 get when running Handbrake to encode a DVD with the AppleTV preset? 2) Does the MBA 2.0 use a PATA connection or a SATA connection to connect to the drives? The MBA 1.0 used a PATA connection which caused some disk access latency at times. 3) Has the construction improved or do you feel the keyboard/screeen/trackpad button etc are better than the MBA 1.0?
