Because I learned a long long time ago that programmers in and of themselves
are not the least bit interesting. For several years their only purpose has
been to dump bootloaders into chips.
So personally I have long thought of programmers as throwaway. $35 for a
PicKit isn't throwaway.
Personally I don't need a programmer. Maybe the PicKit will be useful for
newbies though.
BTW here is a PicKit 1 with Linux page:
