Hi guys, I am weighing in buying the newest macbook air with 8 gigs of ram and 256 ssd. My question is, can someone who own the device post some performance tests/comment etc. about how it fairs under this conditions: have VirtualBox with Ubuntu running inside it (Redis and MongoDB running inside the Ubuntu), also have XCode\Android Studio or WebStorm open and a browser with about 20-30 tabs and a mail client + Spotify. Is the machine responsive is any lag/stutter present and is the Ubuntu UI usable. I will be very grateful if anyone can post his experience with this setup and is the performance good enough for this to be used as a main machine. Thank you.
