You may not like it, but GP has a point: you are probably making better applications than you would if you had access to very fast hardware and massive bandwidth. Because that tends to invite bloat and you are now more or less forced to deal with it yourself rather than to foist it off on the users. So whatever hardware they have they may well find it runs faster than it does on your machine. Rather than the opposite.
I would guess it's probably because the rest of the industry is happily wasting hardware and bandwidth because they can afford it.
If the whole industry had been stuck on hardware and bandwidth from 10 years ago, that most likely wouldn't be a problem.
