So I eagerly waited for the new Macbook Pro refresh to see if Apple does something amazing with the 13'', unfortunately they didn't. So if I have to go with MBP.. I'm left with 15 and 17 inchers. Low end 15'' inch starts at a weight of 5.6 lbs which is slightly higher than the VAIO laptop I'm using right now (5.3 lbs - 14''). Also I don't want to buy the lowend 15'' MBP as for that price it comes with a relatively low power GPU. The highend 15'' is a pretty spectacular laptop but in terms of price wise it is huge (I'll probably upgrade it to hires screen also - which costs around a whopping 2.5k with tax and everything included) Now that you know the background for my question, the actual question - how about 13'' MBA?? I'm mainly a programmer and play games now and then. For programming both 13'' and 15'' are almost the same given the limited screen space, I prefer something much bigger. And for games I'm anyway have an Xbox 360. for MBP cost I could buy 13'' MBA (4GB RAM) + 27'' display which sounds more reasonable given my budget. The questions I would like to know before going with this are: 1. If I connect a external monitor (2560x1600) and use MBA, will it have any impact on performance? If so, what resolution is recommended? 2. Any suggestion on displays that I can buy, ACD is already on my list - suggest me anything less expensive and comparable to it? Thanks in advance!!
