That being said, with Palm OS being old and dead, the only way to experience it is to get your hands on a real device on eBay or its local equivalent in your country of residence. If you go down this route - which I strongly advise everyone to at least look into - try and go for the ultimate Palm device, the Palm T|X. It's the most advanced PDA Palm ever built, and you can pry mine from my cold, dead hands.
Sadly, not everyone has the disposable income, time, will, desire, or any combination thereof, to go out and buy real hardware just to play with a dead operating system and all the hardships that come with it. Since I still want to spread the word of Palm OS, I've been looking into an alternative - namely, the Palm OS Simulator.
