Do you really need to save all those Blu-ray rips of the latest Hollywood blockbusters? Just delete them after you watch them. That way you'll have plenty of room for all those raw uncompressed video.
What use would HTML5 have if Google insists on streaming crystal-clear high-definition unskippable ads to me in a few seconds, but streams the video to me bit-by-bit to the point where it takes five minutes to watch a one minute HD video.
In the film "Out of Time" (a film about a cop, played by Denzel Washington, whose secret girlfriend shows up dead, and the cop keeps his affair with her a secret until he can figure out who "killed" her), there is a scene where Denzel's character has to alter his "dead" lover's phone records to keep his affair with her a secret, so he snatches the records from the fax machine before anyone notices, scans them into his Windows 2000 PC, and uses some low-tech imaging program to delete each of his phone numbers from the list, then sends the altered phone records to the fax machine, all while his partner is on the phone with the phone company getting them to re-fax the records.
His PC ran Windows 2000 with no fancy graphics, and even had a slowly moving progress bar.
