If you could chose between these two laptops, which would you pick? Let's ignore for a moment the fact that the former is about $400 more expensive than the latter. I noticed that I do get page outs in the few GB range with 8 GB, but this is over a day's use or so. I don't notice any slow downs, and my guess would be that writing a few GB *per day* to disk with such fast SSD's must be completely negligible, i.e. take seconds. On the other hand, comparing the two above models, the 2.6 GHz processors 10% increase in speed and turbo boost will be felt at nearly every task. I wonder if that is the reason why Apple offers the 512/8/2.6 in their stores, but not the 256/16/2.3: sure, there may be a small percentage of people who ALWAYS use more than 8 GB of RAM who would feel the 8 GB limit, but the vast majority of users will be fine with that limit 90% of the time, but will notice the 10% or so improvement in CPU power even during much of that 90%. Opinions please!
