What does a modern computer vs. grandmaster game look like?

Actually, there was a 3|0 blitz game played relatively recently in which Hikaru Nakamura actually beat (!) the Rybka engine, see it here:

It is the longest recorded chess game ever played in terms of number of moves, and resulted in a hilarious endgame: K+5B vs. K.
The only reason Hikaru won, however, was due to an exploitation of Rybka's now-fixed 50-move-rule bug, where it mistakenly opens the position.

What was that all about, kleeof?

Have any very high rating GMs played computers publicly in a longer time-setting match lately? What do the games look like? Can humans eek out a draw, or is it all losses?
