I have been a long time lurker, and now deciding on my new computer. I know that it is all based on people's needs, as it is with mine. I'm heading towards the 21.5 2.9Gz with Fusion, but I'm wondering if other users are in a similar situation. My current needs does not envisage 16Gb of Ram, (more like 2-3Gb at the moment) but what of the future.... I have a budget of £1,500, and considering how much the fusion/memory upgrade on the mini is £200/£160 respectively, means I can only do 1 upgrade. I'm not considering an i7 upgrade. 21.5 2.7Gz with 16Gb Memory: £1,260 21.5 2.9Gz with 16Gb Memory: £1,409 21.5 2.9Gz + Fusion (8Gb): £1,449 and to murky the waters further: 27 2.9Gz stock: £1,499 (option to upgrade Ram later if needed). Thoughts?
