Good point on 4 gb. It's probably worth getting it. I certainly do plan to use it to watch movies and I'd like to have a good video editing experience. If I get into it, I'll consider one of the desktop machines later.
I'm not too worried about Access, as I will set it up as a dual boot for Windows to run Office. Some of my specialized software can be operating system specific.
I won't be paying tax on the purchase either. So for me, it's about 20% off of what I would expect to pay at the store. I think this is enough to get me to try one out.
All very good points. I'm leaning toward the 13", 1.83ghz, 4 gb ram, 128gb SSD. That seems to be a good model to tryout.
