Excellent – when my imac first arrived i was a bit clueless of what to do and how the mac works, but after a few weeks you realise it is super easy to use. i have no regrets on buying it, it looks great, works well and the whole time i have had it iv'e never had any problems with viruses! the screens have a lovely glossy look, its easy to set up and move around and i haven't ever had any problems with it! one thing that was annoying was that i had to learn how to use it when i first bought it other than that it has been amazing.
