Hi, Courtney ... Lisa and I are Mac users - laptops and desktops too. Travel with the laptops between Europe and the USA - no problems and because of what I do for work, having a Mac saves me from needing two laptops or a dual boot system. One work of caution - I think the latest Imac desktop comes with a single voltage power supply so if you buy in the USA it might not work on the UK voltage if you ship it, and vice versa. Backward step IMHO, but then it's the laptops that we all carry around and not the full size system.
Balmerhon talks about getting Macs fixed ... well, touch wood, we've not had many problems; we've got - let me see - 6 or 7 macs here and have only had one failure in this millenium ... and that was very recent. In fact I spent yesterday chatting with Apple service about the problem then delivering the machine for a hardware fix to the Western Computers in Bristol; they phoned me back today and confirmed that they're going to replace the main logic board under warranty for me so hopefully we'll have the system back in the reasonable future.
By the way - we have even more PC laptops here than Macs (it's a work thing). Can't comment much on repairs ... we've had a good few disc failures over the years, but we simply order up fresh drives and get Dad to change them as he's better with his hands than we are.
