OK, there's definitely been a lot of different opinions regarding the new MacBook. There are those who are dismissing it completely saying you can't get real done on it and that it's just a toy like an iPad is, while there are others who see that the rMB can be used as a productivity device but don't think it's meant to be someone's only machine.
I for one am going to use it as my main machine. And I have no hesitations about doing so.
Yep, me too. Though, I strongly believe that which machine one uses absolutely depends on what they do. For me, I rarely need ports, never do video editing, rarely edit photos, don't play games, etc...
My main work is writing via Pages, a small amount of spreadsheet work (Numbers) and Keynote presentations. I'm all in for the vision of wirelessly connecting to the devices I need, which I already do on a MBA (printer, HD, projector, AirPlay devices, etc...)
For me, the rMB seems ideal. It seems well suited to teachers, writers, travelers, students, light-use home users, recreational users, etc... But for people who work in contexts requiring robust graphics applications and connection to wired devices, I'm sure the rMBP lineup is a better solution.
