Its running good. I do feel the slow transitions issue that I had with my MacBook, but I feel that over time this will go away. I upgraded the RAM to 1.25GB which is perfect for the machine. Everything is working. All the transparencies are there (There is CoreImage and Animation support). Safari is much snappier than on Tiger, spaces and stacks are good. Fully recommend it for anyone. This machine is ace for £150 you can't go wrong with this! Up-to date for another good two years at least.
