Years ago I wanted to embrace the iPad and kick my heavy notebook to the curb as I travel a lot and was tired of the weight, the thickness, the bulky power supply, the noisy fan, the slow boot times, the crappy battery life, the blurry screen, and all the rest.
That lasted about two weeks.
Right now, my iPad is nothing more than my movie and TV show player on flights and my laying-in-bed web browsing device. I need a real keyboard, I need true multitasking, I need folders and subfolders, I need to build Powerpoints, I need to construct spreadsheets, the iPad just isn't as good as a notebook.
Back to the RMB, it's the perfect notebook as a complimentary tool to the iPad. Having them both is still less than the weight/bulk of my old notebook and now I get the best media device for travel and the best productivity device for travel and couldn't be happier. Thin movie player for an airline tray table, full size keyboard for meetings, retina displays, 18 hours of combined battery life. 12" Retina MacBook + iPad Air = The Apple Dream Team.
