I too am sick of windows based laptops that seem to start acting funny and malfunction, with regular blue screens and physical memory dumps, after around 18 months. I have had it in with a repair shop, who said it was fixed, but still not reliable.
I am not sure whether I am totally jinxed, incompetent, or am having a typical experience of laptops.
I am debating buying a macbook, as I feel the initial outlay may be compensated for with better longevity.
Do people have an opinion on this? Do apples last longer and function more reliably?
