Cubans have been able to get underground and illegal PCs for a while, but the Cuban government only recently lifted the official ban on them. The first publicly-available machines just went on sale Friday. The QTECH PCs are state-approved are only available at a single store. The crowds had a chance to gawk at some not too cutting edge tech. The towers cost $780 and feature Celeron processors, 512MB of RAM, Windows XP, and come with a CRT display.

And even should they buy one, most Cubans won’t be allowed to have Internet access. Silly Cubans, the net is only for certain “trusted officials” and state journalists. The good news is that with computers now legally available, some expect black market prices on more up-to-date gear down the road.

Gibson Guitar Corp. is accusing Activision of violating one of their patents with the popular Guitar Hero series of video games. The patent in question is owned by Gibson since 1999 and involves a system that would let a musician “virtually” participate in a pre-recorded concert while wearing a head-mounted 3D display with speakers. The music played on the instrument would then be recorded on a separate track and available for playback with the rest of the tracks to simulate playing in a concert.

Activision’s Guitar Hero does have a similar premise, however it’s played on a “pretend” plastic guitar and is a game where the player tries to mimic notes in concert represented on the monitor by graphical musicians in a concert. Activision is disputing the claim that they infringe upon Gibson’s patent and is asking the federal court to provide an official ruling.
