It's a complete tablet replacement. It's a tablet without a touchscreen and powerful OS. That's exactly what reviewers have claimed it to be.
I'm telling you because your requirements are more than what you say.
I agree with half of what you're saying, but not the other half.
Yes, he bought the wrong laptop. He needs ports and processing power and the RMB eschews those for the utmost in portability. A few people experiment with the RMB and realize they need ports for legacy connections like SD cards, thumb drives, and VGA projectors and reject the RMB for all the grounds that it exists in the first place as it's the notebook that embraces the cloud and says goodbye to wires. They should have done the research, it happens.
No, the RMB is not a "complete tablet replacement". First, it's a tremendous notebook for those of us who don't game or render 4K videos, it does everything else quickly and efficiently. Powerpoint, Word, Excel, Outlook, Photoshop, these function flawlessly, no hiccups, it's a real notebook. Second, it doesn't fit on an airline tray table along with lunch like a tablet does, it doesn't let you browse email or play a game in bed like a tablet does, it doesn't boot up as quickly as a tablet does, it doesn't retain battery over weeks of downtime like a tablet does.
For those in the know, the 12" Retina MacBook + the iPad Air II = the Apple Dream Team for on-the-go productivity. There are desktop apps and there are iOS apps and they each have a different device that's best to execute them. The combination of the two
still weighs considerably less than a MacBook Pro. Most RMB owners carry both devices.
