I was looking at the 10" netbooks, but realized the screen was too small for what I use laptops for and didn't have enough power or memory for anything more than email & surfing really. And it was hard to read due to size.
I use spreadsheets, websites, & photo software along with surfing & email.
I ended up getting a 13" HP laptop and am happy with the size. Still portable, but not too small that I have to keep scrolling left and right. I use the laptop for travel, in the car, out of the house or just around the house. Its light & has a very good battery. Also has DVD for movies. Netbooks didn't. My DVD drive is actually removeable if I wanted to make the laptop lighter & I was going to be needing it.
I use the desktop for home.
They do make 11" fully functional laptops...just 1" bigger than netbook & they actually work!
