I've been on the fence now for a while in terms of buying an iMac. My 11" MBA is full and not suitable for the photographic stuff I want to do. I'm thinking that a 21" iMac with 1TB fusion and 16GB RAM is the machine I want but am just a little nervous about the possibility of an improved Mac Mini and new display arriving as I just feel that is a bit more flexible than an iMac in upgrade terms - both upgrading the machine itself or upgrading to a new machine in the future. Sadly, my MBA is the 2010 model so there's no real benefit in starting with a TB display and taking an iterative upgrade path, which I have previously considered (TB display first with some external storage and then buy a Mac Mini later). Also I'm wondering if the 2013 model might start arriving in the refurb store soon? After what sort of period do refurbs start showing up? The original plan was to wait until the interest free offer returns to the UK Apple stores but it seems to be late in happening and in any case, I don't think you can use financing in the refurb store. I have discounted the idea of a Mac Pro (nice as it would be) and am wedded to the idea of a desktop solution. The MBA will then serve as a machine for travelling until it dies.
