I embrace the idea of virtualizing old platforms and environments as technology moves forward. It becomes painful when the hardware itself becomes deemed outdated however.
We have a Honeywell WebPad II circa 2001 that we used in our house. It was old windows CE, but allowed us to grab email quick, or pull up a recipe or do a quick google search using wireless.
To make a long story short, the batteries died and I tried to find new ones. It is no longer supported and the only active reference that I could find was a post from some museum in Arizona looking for one for a display of technology.
It is one thing to phase out hardware because the platform they use can be emulated, but I still loose the ability to use the hardware, which in this case is what was important.
SideNote: Do they have a museum for everything in Arizona or what?
I like the idea of having all your old platforms virtualized on a current computer. I've actually played with running ancient software like Digital Research's GEM, and old DOS 1.2 tsr software under emulation just to see if I could. Today's hardware is so far advanced over the original platforms that no emulation hit is too big to hamper the programs... they still run alarmingly fast
