I went into Unity with an open mind, but just couldn't get used to it. Tried for about 2 weeks but it's just too.. different. I wans't getting anything done. Gnome classic for now. Probably back to AwesomeWM soon
It's not that hard. It took me maybe 2-3 hours the first time I did it, and I learned more about Linux than I did the entire year before I had been using Ubuntu. It's not too hard, but it's not set and install, that's all
You can install Windows on that through a USB: http://hardforum.com/showthread.php?t=1381323
You can only max at 2gb of ram because of the Atom processor. It's not the OS limitation, but rather the CPU.
I wasn't a fan of virtual desktops (spaces) but it's come in handy. I have my mail and downloads on one, and then everything else on another. You should look into something like that.
I just have a 15in mbp, but here is what my screen looks like (spaces view)...

Some installers have the Applications folder built into the installer so it does it all...
I would say to check Craigslist.com in your area. Lots of people are getting rid of their netbooks. You should be able to get a nice one from $150 to $220 ish.
I can say, you will love it. I have a netbook that I use with my 15in MacBook Pro and I still use the netbook a good amount.
I have a Bamboo too, and while it's small, it's pretty accurate and nice for the $60 a paid last year. Also, I'm going to school overseas (Korea) and I travel a lot, so having a smaller tablet is perfect for taking with me. I can use it on my MacbookPro and my netbook.
