Pardon my saying so, but it has more pizazz than jacobsonized. Most
every thing I use has been modifies to suit my taste or fancy.

Is the cost of a $300 laptop different from the cost of a $300 bicycle?

Jerry

But isn't the on-topic question which one has more cost from DSP?

Well, the DSP (if there is one) adds much less cost to the laptop than
the CPU does.

Only insofar as two years from now, replacing your $300 bicycle won't
yet have crossed your mind.
You must be right. I still have the $96.50 bicycle I got in 1947.

How much does it weigh?

28 pounds with fenders, carrier, and kick stand. Oh, yes, also the
generator and headlight and the "suitable warning device" that a
policeman made me install when, three mornings running, the same woman
ignored my stentorian warnings. Considering that I weigh about 180
pounds, ten pounds more or less makes little difference. (It's an
avinized Raleigh Lenton Clubman.)

Avinized? I'll have to remember that term.

I missed that the first time - thought it meant something like
"galvanized" ...

Well, of course it's commonplace. CD players, first generation, used
complex tuned/trimmed output filters, and were quickly superseded
by much-cheaper units, with equal or better performance, that used
oversampling (a classic DSP technique).

Every MP3 player, cellphone, digital camera, which h as both digital
and analog functions, uses some kind of DSP if the designers can
find a benefit (usually, that's not hard).
