Oh boy. Have I mentioned my gadget addiction?
I have an Acer One and was comparing it against the Dell Mini 9 prior to purchase. I decided not to go with the Dell (which was a tough call, I love Dell) because their Mini 9 has an unusual keyboard. Someone posted a picture here so you can get a good look at the keyboard lay out:

I didn't want to have to alter my typing, so that was the main decision killer for me.
I *love* my Acer. I wouldn't want to work for long hours with it because yes, it's small, but it's really great for browsing on the go and keeping in touch with work and life. The screen is amazing, they keyboard is comfortable, and all around I really enjoy using it.
Some Walmart, Sam's Club, and Radio Shack stores have these in stock if you want to look, touch and feel.
