I've got to admit, the £358 price tag of the lowest-spec mini (with Educational discount) has really caught my attention, but my question is this: how sluggish will it really be? I am currently chugging along with a 2006 Core Duo mini which is growing slower and slower with each passing day, so I need to buy something soon. I'm extremely tempted by the 5K iMac but am the cautious sort who would rather wait a year or two for the various kinks to be ironed out, so I'm considering buying the cheapest Mini to last until I'm sure the 5K iMac isn't riddled with problems. In your opinion, what would be the biggest limitations of the low-end Mini? Would I see lag when performing everyday tasks, such as word processing and light photoshopping? Would I be an idiot to spend £350 on this machine?
