For those lucky enough to have pre-ordered the SB, I have one still open question that concerns me that I wonder if someone could answer: As a commuter and a person on the go with a well packed Timbuk2 bag, I worry that the fulcrum hinge will have to endure some pressure in my bag. With a laptop that closes flat, or my SP3, as long as the screens are protected I'm not really concerned because pressure is transferred evenly through the device. Ala as long as the screen can take the weight, no biggie... I'm worried that with the hinge, that it will have a 'breaking point' quite literally. I would plan to get Microsoft's warranty coverage which has been excellent for me in the past, but still a lingering concern of how well once people receive it, it can hold up in a laptop bag with a lot of weight shifts and things in some cases 'sitting on top of it' sorta speak.
