Well for me I made the MOS choice after a long long thought process. I've had an Amiga as long as I can remember. This just feels more like an Amiga to me and I can still run all the Amiga Software I did on my A3000, but at greater speeds and in more cases even more stable! OS4 will have a hard time keeping up I think, that and the fact it keeps getting sold off turned me away from it.
