My wife and I have a shared MacBook Air, 13 inch, mid 2011. I use it for iOS development, she takes it to meetings where she has a part time minutes taking gig. The sharing has lately seen limitations, so we are considering getting another MacBook Air. She would also use it to replace her aging Mac Mini, which lately has seen software upgrade limitations. To replace the Mac Mini with the MacBook Air, we are thinking of the following routine: Get a mini DVI to VGA adapter to attach the MacBook Air to the Samsung monitor. Plug the USB hub into the MacBook Air. This would take care of the keyboard, mouse and Time Machine hard drive. I know there are wireless solutions but we already have the wired versions and aren't excited about managing the batteries and would like to keep the cost down. Plug in the MacBook Air charger. We've gotten to appreciate the MacBook Air and the job it's been doing for us. The $$ is OK and while more powerful options are available, it's been working well for us. Any comments, advice, would be appreciated.
