Hi all, I currently have a lat 2010 iMac 27in. Time is approaching to look at a replacement, but here's the dilemma....I work from home quite a bit and I use my current iMac as an external monitor for my work windows laptop. It works great, Displayport/Mini DP adapter and the iMac turns into a great monitor. The issue is the new iMacs have closed this possibility as Apple tends to do so new iMacs cannot accept a non thunderbolt device. So there is now way and this has been debated endlessly on the internet, to hook up a windows laptop to the iMac to use as a monitor. Very silly from Apple as there is no way I am the only one who wants to do this. So I have to look at other options. Mac Mini and a new QHD monitor but the Mac Mini is a worry because it's seems a bit weak and of course nothing is upgradable in that device now. So I'm now looking at a MBP to use as my desktop replacement allied to a good monitor like the Asus MX27UQ. My use is pretty basic. I don't do any taxing tasks like video or photo editing or gaming. To me, the MBP 13in with 512GB SSD and 16GB of RAM seems the best choice and more than enough for my needs. Question is, does the 15in with the quad core etc make more sense from a future proof aspect? I won't be lugging this laptop around anywhere so portability is not an issue. The 15in possible also can dissipate heat better I expect as it's bigger as well. Main crux of my situation is this, is the MBP 13in a genuine desktop replacement for the iMac?
