Re: 'NetBook' - exactly.
Just by way of a comment, I run a network of MacBook Pros. They're now mostly 5 years old, are all still solid, reliable and quick. The purchase price, IMO, is well justified based on my experiences in previous places using bog standard Wintel laptops which if they last that long, are all creaky and slow. I've run many OSs on mine (currently mostly use Windows for some VBA stuff I'm doing) and I've no reason to assume you can't put any OS you like on this new MacBook. Expensive, yes, but it'll probably last. Limited ports, yes, but in the office, a hub would fix that and out of it I don't use them. For me? Probably not but mostly because I don't need a new machine right now.
