So come the end of the year, im going to be buying either a 21.5'' 2013 Haswell iMac with a SSD or a 2013 Haswell Macbook Pro Retina 15''. Now assuming that both will feature a 1gb dgpu, which would be better? For day to day use, the 21.5'' will be fine, but when gaming, which i intend on doing, i think the 21.5 would be a little small no? I have a 42'' tv in the room next door. So would it be better for me to buy the iMac and just play on the 21.5 and if i want run a long hdmi cord to the tv. Or buy a rmbp, for general school work use the laptop monitor, and than when i want to game, take it to the lounge room and play via hdmi on to the tv? What would be better. Also, what is the range of the Apple TV airplay, would it be possibly to game via the iMac on to the tv in another room. Thanks.
