I'm looking for some notebook that will run on Ubuntu perfectly. I like LENOVO IdeaPad Z570, but I'm not sure how it will perform on Ubuntu.

I heard people are complaining about wireless problems.

Here is full configuraion:

 Processor  Intel Core i5 2430M 2.4GHz - 3.0GHz
Chipset Intel HM65 Express
Memory  4GB DDR3 1333MHz
Graphics    NVIDIA GeForce GT 520M 1GB
HDD 750GB SATA II
Wireless 802.11b/g/n, Bluetooth 2.1
Network adapter Ethernet LAN 10/100Mbps
Ports VGA, HDMI, 3x USB 2.0, eSATA

Does anyone have experience with this model? Any problems noted?

I heard there is a test suite, how can I install it? Maybe I can boot live CD and try it myself before buying it. But, unfortunately, sometimes something works on live CD, but not when you install it.

I guess critical components here are graphics and wireless.

Any feedback would be appreciated.
