I have been running the beta for a while now. If you have supported hardware it's not bad. I don't like all the added security but with a little effort you can figure out how to turn it off.
I use all the major platforms. I am writing this on a new MacBook Pro that I convinced my company to buy for me. =) All in all, each of the platforms including the Amiga have their pros and cons. Anyone who cannot admit as much is overly biased towards their platform of choice.
Nonetheless if you are used to an Amiga there will be many niceties. If you are used to WinXP or Mac OS X the novelty factor won't be quite as big. But like everything new it has its merits and faults.
Have fun with it. When you get frustrated, and you will, remember there are others out there that have probably solved your problems. Use google.
