...I've realized over the years that for me, cost justification has become extremely important in my decisions. It's hard to justify the MBA when it peaked at $1800 yet was a fraction of the horsepower of the lowest end MacBook Pro. It feels like you're paying for form over function, and if that's how people are comfortable using their money, so be it. I just don't agree with it.
Agree that your perception is your reality. From my perspective, its not quite a "cost justification" in as much as it is an assessment of
value, since cost and value aren't interchangeable terms AFAIC.
You have a few extra pounds, so what?
I'm not asking you (or anyone else) to agree with where I choose to place my limits - just that a limit exists for everyone. If you want to go break your back hauling more, that's your business...you too will eventually hit your tolerance limit.
And FYI, please note that I find your
'seriously out of shape' insinuation to be offensive: I made it quite clear that it wasn't just a laptop by itself that was the metric of interest, but was one component contributing to a larger system.
Besides, its not necessarily only about personal "strength" limits - when one gets off the beaten path, flight weight limits invariably go down: in Tanzania, the bush plane's limit are 15kg (33lbs) total per person (all bags, including any form of a carry-on) and traditional overweight fees don't exist: you fork over the cash to literaly buy a second seat.
You're underestimating the "few extra pounds" which would justify calling the MBA "weighing yet a fraction of the MBP" and overestimating the horsepower (2.4 resp 2.66 vs. 2.13 with the same self Core2Duo). By far.
In numbers: MBA weighs 2/3 (that's 67%) of the 13" MBP at 80% of the processor speed comparing top models each.
So, lets talk about money, or value for it. Standard configuration makes the MBA 17% more expensive than the MBP. But you don't get an SSD for the MBP. Which makes a lot in costs (and performance). Taking the SSD option for the MBP makes them exactly equally expensive.
Interesting insight on the value equasion; thanks.
Here's another one: this is a real-world problem, so I'm leaving it very much open to the group to suggest equally capable yet lighter alternatives.
The task is simple: provide redundant data backups for my Underwater dSLR camera system. I'm figuring an upper limit of around 7K images before I'll be back home, which works out to a data storage requirement of nearly 300GB.
Yes, three hundred gigabytes.
Granted, it would be a nice-to-have a laptop along with me, but my carry-on bag is already "full of camera" (and just camera) and it already weighs 28lbs.
Yes, twenty-eight pounds.
The benchmark to beat is a combination of 160GB worth of CF cards and two (redundancy) 128GB Hyperdrive HD80's, which comes to 2lbs. I already owned most of this, but to buy it all new today would be around $1600. If this sounds crazy expensive, do realize that this is roughly only 20% of the cost of the overall UW camera system.
Yes, only twenty percent.
