Finally went by my Apple Store to try on the watch and check out the new macbook. I am a systems architect for a cloud computing company. I use a rMBP exclusively to do all my work, code, config, installs, etc. All of this is done server side SSH on big beefy AIX servers that run into the $1million budget range. With that being said, I work remotely from my couch or FUF for the past 8 years. I saw the space gray rMB in the store and it was love at first sight. I got on and popped up some apps, played around with it and instantly loved the keyboard, trackpad and the footprint of this dead sexy new machine. I have the base model rMBP as my primary machine and I rarely push it. This new rMB is just the nicest laptop I have ever seen. I use time machine on an external drive and crash plan for backups, I don't see an issue with the single port for me. After 10 mins of playing around, I came home and ordered the 1.1 256GB space gray without a second thought from best buy. Sold. This was a no brainer due to portability and technology improvements that I will actually use over raw power I do not need. YMMV.
