I have already got a custom windows 7 system as listed in my signature. I was originally thinking of selling it and getting a new iMac. Now that I have had a bit more time to read opinions of them I don't know if it is worth getting as it will be near enough the same spec as I have now minus the screen (this could be upgraded) If you are familiar with the u2711 you will know all about the AG coating. I intend to use the machine for my masters in architecture and I am not sure which setup would best benefit me giving that there would be some cash spare if I kept my current system. Although it could be debated that I would be better off with the iMac or even mbp? I don't just want the machine to last for the course but go on after that so it's got to last at least 5 years to make economic sense or retain some value in three years time. There is known problems with both options. Briefly iMacs: can't run as much architecture software, can't be repaired without apple cover or much upgraded, expensive. Briefly PC's: windows os can have random driver related blue screens on a brand new system, take up a lot of space and are hard to move, further behind technology speaking, general stability problems are the worst for me I dont want my system going down all the time. Given the choise which one should I go for given that with the spare cash I could buy an A1 plotter without being broke.
