Hi everyone, My current situation is this, I have a late 2010 11'' MBA running snow (slow?) leopard, it can't run any OS higher than that because it lags like hell. I really plan to keep using this machine for another 2 years as people say MacBooks can last 5 years or more. The thing is this screen 11.6'' is way too small for my work. I am a stock trader that live between different countries. I don't think it is ideally possible to connect this MBA onto a larger monitor because it will lag the machine even more. I have considered other computers like the iMac, but I can't bring that with me. Or rMBP - the screen is still too small on those, so I still need to buy another screen, which would drive up the cost. Therefore I am seriously thinking about getting a Mac Mini so I can bring it between different countries for work & play. I don't necessarily need a super powerful computer like many of you for photoshop/video editing, but I do need to open up 40+ Chrome browsers at once on top of some other not too demanding softwares. I am think about the Mac Mini setup would be like this: 4gb RAM, 500gb Hard drive, with an 23'' ASUS MX239H. I can get another screen later when I need to as well. I also need to pay for an Apple wireless keyboard + magic mouse, which would add to the cost as well. I can probably upgrade the ram with an SSD later on if the base model MM lags. I ran a cost analysis, Base model Mac Mini full setup: ~US$930 Base model 21'' iMac: ~US$1400 Mid Range 13'' rMBP: ~US$1500 + Monitor = US$1750 Base model 11'' MBA + Monitor: ~US$1250 Base model 13'' MBA + Monitor: ~US$1350 Pretty much the MM is the cheapest of all options, I am still not sure. am I not seeing everything clearly? Please enlighten me.
