Well I see what you mean, the engines handle this - so no advantage here.

It is quirky on Win7 when it comes to Aero afaik. BUT that's something that
SDL can work out really.

Well I usually like to be ready before and update as the API updates.
Obviosuly I agree - it only becomes really stable a few iterations in (e.g.
Direct3D - although that still changes).

Anyway as I said if you think it is cool, well give it a try. Whether we can

 Well you're probably right. If SDL does the job on Win7 - why bother? :)
