I owned a 600m, it bent under pressure. I was shocked. I paid $1200 for it then I expect something worth $1200, not some cheap flimsy mass produced garbage. Bear in mind I care much were my money goes. The 300m is made from Samsung. I did also own a 180B5 VprMatrix which is an Samsung notebook also. I really loved the keyboard. It was and is comparable to my current T40.
