Hello! Im currently in the market for a new laptop. My current has served me remarkably well for the past few years. I'm using a 2.0 GHZ Core Duo White Macbook with 4 GB of ram. I'm a physician, and I've primarily used it to conduct day-to-day activities. The Microsoft Office suite of applications, iWork suite, iLife suite, surfing the web, watching NetFlix, iChat + video conferencing are just a few examples of applications that get a lot of use. I'm particularily interested in how iWork / Office and iPhoto run. My current laptop handles all of these just fine. That said, I found myself with a little disposable income and feel its time for an upgrade. I've been seriously considering the 11.6 inch Macbook Air for its portability, and can easy lug it around on morning rounds with me. The alternative would be a 13" Macbook Pro. Because the latter isn't as portable, I imagine myself leaving it in the office. Will the 11.6 inch macbook air handle these tasks? Will I notice a performance increase or decrease going from a 2.0 GHZ Core Duo + 4GB to a machine running 1.6 GHZ Core 2 Due + 4 GB ram? Will the difference be significant? Have you noticed any "performance issues" (i.e. input lag etc) when running these applications? What is your opinion on longevity? Any insight you can provide would be very helpful!
