laptops + help protecting framed art

::::::FRAMED ARTWORK IN SUN?::::::
Does anyone have experience with putting up original artwork (like animation cels) in a kindof sunny spot? will UV glass protect the artwork enough?

EDIT: looks like the consensus is no cels anywhere near the sun, ever. (Maybe I can find a bedroom that's darker and make it my art room?) I have some stuff I've been keeping in a celbook for years, I'd like to finally frame them sometime in the next couple years. lol.

::::::LAPTOP::::::
Mitch and I need to finally get a laptop. I'm leaning towards a MAC because I'm used to them and I like their ease of compatibility for presentations at conventions. We'd need one of the new MACs that can run PC progams, too.

What about having internet anywhere you go? How does that work? Does it only work when you hit a "hotspot"? I've never had one, so I have no idea. (in fact I haven't had a laptop since college!) Mitch would need to be able to check his email and play games on a laptop on the train, but it seems the train here doesn't have internet yet.

Thoughts, suggestions, please!
