you're asking if i like one operating system, or a piece of hardware/computer?
Having used a Mac for six years, after being persuaded by my son to change, I don't think I would go back to PCs and Windows now. Every software update, even minor ones, on a PC was always an almighty three hour wrestling match with many incompatibilities, restores and crashes. I haven't had a single such episode with the Mac in the last six years, and plenty of things have been changed and updated. They also seem to attract much less in the way of viruses or malware.
when was windows better than mac?
