Reports Of Surface Book And Surface Pro 4 Problems Proliferate
 

I'd like to think that these are just isolated incidents, as I'd hate to see Microsoft make a serious fumble after the momentum they've managed to achieve for their new Surface lineup. There are reports of Surface Book freezes all over the Web. Tweetium Windows author, former developer at Microsoft and all-around guru Brandon Paddock @BrandonLive had a series of freezes and hangs with the laptop, at least some of which were apparently caused by the Intel graphics card.
