Greetings, I know the new MacBook Air is pretty close in specs to the M11X R1. My R1 has a SU4100 (1.3GHz) CPU (which overclocks to 1.7 in the BIOS), 7200 RPM drive, 2GB RAM, etc. Is there enough of a performance boost (from SSD memory) to justify switching from the M11X to the Air, or would it be wiser to go with the R2 (i7, etc)? I believe other than going to SSD, there's not much difference in CPU, video, or memory speeds. I've probably answered my own question, but can anyone chime in? Thanks!
