i reckon we will be seeing "media center" pcs built into televisions, or the whole thing the size of a hddvd with a minimal heatsink, heatpipes and a coupla fans (or they may even utilise liquid cooling).
this way, i reckon we will be going back to the apple designs (all in one computers inc the monitor), but at the same slimness as of todays' TFTs.
at least for the general/media person.
