Summary: I'll second what another reviewer said, add this to your order for easy connecting, you'll be glad you did: StarTech USB2HABM3RA 3 ft.
Pros: Got for my wife who uses laptop for work more than multi-screen desktop. Works awesome for adding a screen for her work. Movies look great on it, too. Still can't believe this monitor works so well for so cheap via a USB port. Like Star Trek, only real. Can't beat it for the price.
Cons: Cons? 70 bones and free shipping? You got to be kidding!
Summary: Some people have bashed this thing for the mini-USB port breaking. I have used this monitor rather heavily for the past four months. I have babied this thing -- kept it in a case, been careful not to pull on the cord, etc. It is still going strong! I simply understand that the jack may be a weak spot, so I am treating it accordingly. No problems so far.
Pros: This is a great 2nd monitor. The size is nice for throwing in a laptop bag. The fact that it can be used portrait or landscape is a nice bonus.
Cons: The brightness is not adjustable -- not really a big deal, but I thought that I would mention it. The stand does not allow much adjustment of the viewing angle -- once again, not a big deal.
