I still have the first Sony Walkman Sports AM/FM-Stereo Cassette machine that I bought in 1986. If memory serves, it cost me about $215 Canadian, and that was on sale! These days something similar can be found for about $35.

If this concept catches fire, and it certainly deserves to, I expect to see a fairly versatile stompbox version on the market fairly soon. Maybe two years?

Take a look around on that Amptone site. There are a [u]lot[/u] of people working on this. The first ones on the market are always very expensive, and need some fine-tuning as to which features are important to the end user. The London Power product is aimed at engineers working in a studio. Something gig-ready is sure to follow, from somebody.
