I'm going to get a mac laptop for a few reasons:
1) synergies and scaling with other devices in my home + office environment.
2) i want to get the respect of my peers and the amorous advances of women the coffee shop down the street.
3) i want to see if they really are more reliable than the numerous PC laptops i've gone through in my day.
Besides the usual productivity apps i'd like to install a few games. The most graphically demanding game i'd want to play would be Europa Universalis III or Medieval 2: Total War while road warrioring.
My current thoughts:
I don't need to spend $1800+ on a laptop.
So i'm considering:
The basic MacBook, the 13" MacBook Pro, and the cheaper 11" or 13" Airs.
Between the MacBook (long due for a refresh, right?) and the Airs, it seems like the Air wins out - they both have 2GB of RAM, and a 320M integrated graphics chip. The MB has a 2.4ghz dual core compared to the Air's 1.4. I'm thinking the bottleneck for anything demanding is going to be that 320M rather than the processor speed, right?
So with the MB ruled out, i'm comparing the Air to the MBP: The differences are in processor speed - again, it shouldn't matter as the Pro has a 320M IGP too. The real differences seem to be in memory. I don't care one bit about storage space, which means SSD is more appealing, ceteris parabus. So I guess it boils down to this: is the 2GB memory advantage of the 13" MBP's as compared to the Air noticable while trying to run Office apps - i.e. multitasking between multiple large excel and word files while running a Citrix client in the background. If there is a major difference in perf. with the 2GB RAM, i'd think that tips things squarely in favor of the MBP as long as the 13" isn't crushingly heavy, etc.
If there's really no perf. difference for what i'm envisioning, then there are a few other comparisons: the glass multi-touch versus the MBP's interface (i don't want to pack a mouse) and battery life (the air is shorter but not materially shorter for me).
After that we're down to comparing apples and oranges - the screen real-estate/price trade off between the 11" and 13" models, the SSD, and the weight/durability/style differences.
I'd appreciate insight into the the decisions and thoughts of others making this decision.
