Another option, which doesn't require as much swinging and jumping around, but which is technologically closer to "Jetson's" level gear is Sony's PlayStation 3. The PlayStation 3 is darn near a supercomputer. (In fact, you can use a Gigabit Switch to tie 8 of them together and make an actual, serious PS3 based supercomputer cluster, capable of running at around 200 GigaFlops.)
The PlayStation 3 also has the potential help your favorite senior citizen live longer, because Sony has teamed up with Stanford University to incorporate Stanford's Folding@home Protein Folding Distributed Computing project into the PlayStation 3's Operating System. With this code, the seriously powerful PlayStation 3 can work on Protein Folding Science to help find cures for Alzheimer's, Parkinson's and Huntington's diseases and various forms of cancer caused by misfolding proteins. (When it's not playing BlueRay DVDs or graphically stunning games...)
FreeRepublic has their own Folding Team, Free Republic Folders - A Tribute to Ronald Reagan, where you can learn about the project and devote your spare Mac, PC or PS3 cycles to, Here. It's painless and fun! FreeRepublic's Folding Team is presently in 52nd place, out of thousands of teams world wide. Join us!
