While it's easy to be pissed at Samsung for capitalizing on this, I think it's worth remembering that if they didn't raise prices to where supply ~ = demand, there'd be shortages and you wouldn't be able to buy memory at any price (beyond scalpers). It's small consolation though.

To me the more interesting question is, how high are the barriers to entry? Surely there have to be companies eyeing this and wanting a piece of the pie. Is it really just extremely hard to get into production? Or even to expand existing production capacity? Is anyone coming up with clever solutions?

Any startup would envy this rate of growth:)
