The tryout teaches you a spec then you do the legion scenario , then when you get to Dalaran it gives you 10 minutes and logs you out . <| sep |> All hail you ! <| sep |> Yes , they ' re hard to avoid , and work on all public transportation in the whole country trams , buses , trains , metro etc . <| sep |> Eh , 2012 was the first year of retina MBPs soldered RAM , and the last year of nonretina ones DIMM slots . So it ' s been around a while . Plus , while technically upgradeable on the iMacs , it ' s a major PITA on the 21 version you have to remove the screen . Very easy on a lot of the 27 iMacs and older Mac Minis though . I ' m kinda surprised that worked decently , to be honest . Probably the worst I ' ve done is use a Dell Inspiron 2560 with 256 MB RAM , run Ubuntu whatever the current version was in 2008 , and then virtualize Windows 2000 within that 96 MB . Still usable , amazingly . That computer was a piece of garbage even at the time that barely ran XP . Note on the overheating bit I have a t 450 s only a 5200 U and IGP , but 12 GB and an SSD , and was running the old NFS HP 3 game under a W 2 K VM . No overheating at all , even though those old games hog every CPU cycle they can get for some reason come on , one emulated core on a modern CPU is piles faster than the Pentium 1 ' s it was designed for . . It ' s up to you , but DDR 3 RAM is so cheap that you may as well upgrade your machine to 4 GB or 8 GB .
