This is pretty identical to mine, so I have a natural bias towards this (and the only one I took seriously). There's something to be said for simplicity, but too simple is just not realistic. For example, in the first picture, it's just a laptop on a table. No pen, no paper, no earphones, no mouse (!). There isn't even a power cable. I know it's to make it look clean, but like I said - not realistic.
