But you can buy fpga boards with pcie bridges, doesn't it solve the problem ?

Also the main problem that prevents fpga's being used for all kinds of cool stuff is that it's really hard to program. And many companies are trying to solve it - yet without great success.

And to solve this problem(in a decent but not in the most efficient way), one doesn't have to have the internals of the fpga, no?
