You can't even update Commodore OS now..
There was only two things I liked from them..
1 C64x(I wouldn't buy one to pricey,I have a c64 Keyrah now,thanks to Cheese on the Commodore-Amiga Forum)
2 Commodore OS (still a 32 bit version out and being updated,I made a copy of it so it would work on 32bit and to see how easy it was,something to do I suppose.lol)
When they started doing Amiga's it was getting to be abit of a joke.(Pc in a chinees pc case with a Amiga,C= Badges on)..mmm
What going to happen to C= OS Now..??
It's just Linux Mint using Gnome 2 with some Compiz effects etc. (

If you are that keen there is nothing to stop you from grabbing Linux Mint with the Mate desktop and taking the existing customisations and applying the to the newer versions of Linux Mint. Linux Mint comes in 32bit and 64bit flavours.
