Bought for an EeePC - Connects via USB A-mini and is powered via USB, so no need for a bulky adaptor! And it actually works quite well unlike some others I've tried (Which sortof work off USB power but need external power for stability, esp. when writing!)
Only criticism is that the writing speed really sucks.
I bought this as a company to my white netbook 3 years ago. Through thick and thin this drive is still chugging along, still amazed that it runs purely of USB for most applications. As much as I'd love to see the total elimniation of optical media, drives like this make using discs almost user freindly.
