The Acer Aspire One is a 8.9" display netbook ( or mini laptop ) . The base Acer Aspire One, which includes an 8GB SSD and Linux starts at $329 available at amazon.com, which is the cheapest one that has the Intel Atom processor. Below is the Aspire one review from my opinion.

Display
It has a 8.9" , 1024 x 600-pixel resolution , LED Display. The LED backlit display on the Acer Aspire One is very bright and vibrant. The white levels are very clear, leaning towards the cooler or bluer side.

Design
The design of the Acer Aspire One is very sleek with softly rounded edges and a smooth glossy surface that is comfortable to hold when closed. It is accented with distinctive details, such as the attractive orange hinge ring. What I didn’t like is that the Acer Aspire one has a gap between the bottom of the display and the netbook base.
The Build quality looks solid and doesn't look like a budget mini laptop.

Keyboard and Touchpad
I really like the keyboard. It's a great size and doesn't feel crunched up in order to hit a form factor. In fact, because it provides solid key response and a wide gap between buttons, I proclaim this one of the few netbooks to be fully adult-hand friendly

Operating System
The mini laptop comes with either a Linpus Linux or Windows XP operating system.

Battery
If I turn down the brightness, switch off wifi, and use non-CPU intensive applications, I can squeeze a little over 2.5 hours

Conslusion
Pros:
- Great Keyboard
considering the mini laptop's size compare with Eee PC 900 or Eee PC901
-
Low Price. Excellent value for money.
- Attractive, slim design. Doesn't look like a budget laptop.

Con:
- Very hard for upgrades.
- Noisy cooling fan.
