I normally would agree with your low valuation sentiments, but the competition is really fierce (Roku, AppleTV, even Ouya) and I haven't seen more than one Boxee out in the wild.
Initially I wrote it using 2 div's (one for the segment and one for the gap) so it would work in ie8, but I opted to go with one div, since its cleaner DOM-wise.
I tend to use it for sites that have low line-heights. Like this site. The wide page and low line-height make it really hard for me to read. For reading content I'd say a min of 160% line-height.
The general consensus is that they timed it to coincide with Apple's announcement, so that the news of them laying off employees would be buried by all the Apple press.
I think it has more to do with getting the cuts out of the way before their Q3 earnings report comes out tomorrow. Facebook just mentioned in their earnings call this afternoon that they've been hit by a 20% YoY drop in revenue from Zynga, so you know Zynga's results are going to be bad.
