Michael, I second that.

While ISP/IAP may not be the cats miauw for low cost million unit designs I can not comprehend anyone amateur or low unit count not using the ISP/IAP chips.

I have (with more than 2000 uCs used a month) switched to ISP/IAP simply to allow field upgrades by simple means.

Still we see "how do I build a programmer" and things like the above.

Evidently, even with the extremely fast progression in chip design some do still believe that what was right 10 years ago still is.
