Just not enough HD and the speed of these netbooks is ridiculously slower than slowest. Just start it up and see how long it takes to hookup to the internet. If you like small, light, cheap, something just for checking your email, and a keyboard that you can't type on, then I say get it. Some of you may say that it feels just like a regular keyboard, but after missing a couple of keys and watching your fingers slide off the side of the entire keyboard, hopefully you'll think twice about the move...
I purchased an MSI Wind just after Christmas, and it is nothing as you describe. I had XP & OS X loaded on it for awhile and have recently installed Windows 7. Each of the operating systems I've tried boot up fast and connect to my wifi router (at work or home) very quickly. I wouldn't use it to type a really long document or use something like Photoshop heavily, and it doesn't handle 720p mkv files or HD on Hulu. But it handles DVD-quality MPEG2 and AVI files without a problem. It is very fast at browsing the web.
These atom processors are designed to run non-labor intensive programs very fast with very low battery consumption.
I have the U100 version of the Wind. It has a 160GB hard drive, and I added an extra GB of RAM to put me at 2GB. My battery is a 6 cell and easily lasts 4.5 hours unless I spent the whole time putting the machine through its paces or turned the display to the highest setting (too bright anyway).
If you want a netbook that runs OS X very well, you want the MSI Wind, Dell Mini 9, or Advent (can't remember the model number). These are all basically the same machine having been manufactured from the same company. The MSI Wind forums are fantastic for information. There are unofficial drivers out for the Wind and OS X. The only thing I am waiting on is an audio driver to allow the headphone jack to work without the workarounds that have been created. The only thing I don't care for as much is the touchpad. I have installed new drivers, and it is much better is OS X than it was. But it obviously doesn't compare to the Macbook (and I wouldn't expect it to).

I already have the netbook, and I am looking to purchase a MBA. I think they definately have different purposes. After using OS X on my Wind, I have decided to get a Macbook or MBA as my primary computer and ditching my PC. My only dilemma is whether the revB MBA can be my primary computer or not.
But anyway, get a netbook. They are a lot of fun. I take mine places that I wouldn't take a MBA just because it isn't as valuable and the footprint is much smaller even if it is thicker and only slighty lighter.
