Well, it depends what you mean by "good". The Acer Aspire One is decent, and most models are less than $300 (but you only get 1 GB RAM).
This might be an ideal solution. When I meant "good," I mostly meant "good build quality," or more to the point, "won't explode." 1 GB RAM should probably be enough to hold me over. In all likelihood, I would wipe it and stick some Linux distro on it. Again, I only plan on using it for word processing, web browsing, and emulation of simple things like Game Boy games, so I don't need a super duper gaming netbook.
Edited:
Looks like it's gonna be 2x4GB then.
Bit of a post-question question: I'm looking at two 8GB sets of Mushkin memory on Newegg. One has their wavy-style heat spreader, and the other has the ridge-style heatspreader. Identical specs, identical price. Is there going to be any sort of difference there, or is it just a styling choice?
It's largely aesthetic. In practice it really shouldn't make a difference.
