These labels - netbook, notebook, laptop, ultraportable are somewhat arbitrary. A netbook is a perception. Is it a cheap computer, a small computer, a slow computer? Some/All/none of the above? What do you need? What features matter?

I have a Acer 1810T with a dual core SU7300 processor, running W7 64, with 4GB RAM and 300+ GB HD. Here's how I rate it:

1) small as an ultraportable <3lb
2) a heck of a lot cheaper (I paid $599 when it came out)
3) pretty powerful (hell, I used a Compaq 386 sx16 with a 20MB HD and thought it was great in 1988 and do you remember having a CD30 with thermal paper to dial up connect at 1200 bps if you were lucky and 300bps?)
it's as fast as anything I've had at this weight

This thing is my primary computer and I travel with it (100k+/yr) and I wouldn't spend less for a "full size" laptop. I had an Atom netbook and it was lame. If you plot a dual core SU7300 on price, size and performance, you'll realize that it's off the charts. one might call it a netbook - based on size or price or a laptop based on performance. I just call it the best deal out there.

So, my (hearty/strong) recommendation. Take a good hard look at the SU7300 dual core netbooks - forget the labels and just consider the price, performance, weight, etc. I think if you do, you'll see that they are a GREAT deal.
