I've just ordered this system:
Mac Mini
Intel Core i7 (Quad Core, 2.3 GHz Turbo, 6MB)
Mavericks
4 GB Ram
Intel HD Graphics 4000
I intended to add a ssd but apple store said I didn't need it for Xcode, webbrowsing, word processing and movie watching. Actually they even said the i5 would be sufficient but I decided on the i7. They really helped me out! I will put in more ram (apple store suggested 8, but I'm going for 16). I'm also grateful for all the tips received on the forum
Nice, I think at this point I'm more or less just waiting for either the update or discontinue news. Either case I'll make sure I secure myself a mac mini.
