Right now manufacturers are rethinking the netbook concept. Current models don't really have low enough prices to justify their existence when low-end traditional laptops have practically the same prices. This category is probably going to be redefined as the ChromeOS boxes for $200-$250. Personally, I'm buying a Wifi Xoom tablet tomorrow.
Price. In this case "enhance" == triple the price of a decent atom netbook. The entry level Macbook Air starts at about $1000, way over the poster's $300 budget.
I've got a Toshiba NB255 that's great for my needs. I'm in front of my development PC at work 80% of the time I'm in the office, and it's fine for basic use when I'm at home. I try not to spend too much time behind a screen at home, though. For email and web access it's great, and small enough I can keep it in my coffee table in front of my couch. I wouldn't try video editing or software development on it, but I can't remember the last time I needed to do either of those at home anyway.
I don't have a netbook, but I am seriously considering it. Apparently it is an option for me through UBM Electronics.
I am in the travelling light and long battery life please use case....but would I miss the larger screen size in the office? I regularly have 10 or 15 browser windows open.
There's an old saying: Those that can, do; those that can't, teach; and those that can't teach, write about it.
Could that be paraphrased to: Those that can, have a desktop/laptop; and those that can't, could benefit from a netbook?
Netbooks are NOT replacements for your main machine -- whether laptop or desktop. Even the latest multi-core and multi-thread machines don't have the power for serious work. On top of that you have a small, limited-resolution screen.
Netbooks are great when you are travelling, or moving around a lot, and need to access several documents, images, media files. They're also very good for internet access of email and news sites. I travel for business and the very compact and light netbook is what I prefer to take along, especially to meetings and presentations. Battery life is great for long flights and days full of meetings.
If you are doing EE design work, software development, graphics, video processing, etc. you should get a more powerful machine. If you are going to have only one computer, save up for a more capable laptop.
I do not own a notebook and current could not justify the cost. My usage would primarily consist of: design tools and email. I am not sure that a regular laptop/desktop could be beat for these normal type of applications. Can anyone tell me what the "best case usage" is for a netbook? Just wondering.
