I recently purchased a new mini, base level 2014 model. I think performance is very poor. If you want to do one thing at a time, it is just OK, try and do more than one thing at a time, massive delays, loads of the old beach all spinning away. I am doing nothing more than itunes, email (via the mail client) and web browsing, but even with these basic activities the machine struggles, how I wish I had not purchased the entry level unit. A warning to all, if you buy a mini, please spend a little more and get one better specified than the entry level unit. Frankly I am surprised Apple released it like this, and even more surprised they got away with it. This is not what I expected from Apple.
