2010 13" MPA Screen flickering & Frozen Screen

Guys,

I've had the new macbook air just two days now. Turned it on this morning, used it for like 5 minutes and the screen just started flickering, and the whole machine just froze on me! Had to do a system reset, but I'm a little concerned after spending over a grand on this macbook! Has anyone else experienced this? I'm actually thinking about returning the machine..

I've ordered a replacement, even though it's only happened the once. Apple support is great.
