Some of us prefer to amortize a couple of $thousand extra over 5-7 years to spend the next 5-7 years using best hardware rather than using low end hardware. The cost delta is less than an Starbuck's plain black coffee every day.
Agreed the MBA and the Neo are great value. Each of us chooses.
If you're doing it that way and pushing to more than 5 years you're probably getting worse performance on average over time than spending a couple of grand less and replacing more frequently, like every 3-5.
If you're using a 7 year old machine at any point, you're well behind current low-mid range performance at that point.
