AVR-Chat

3 or 4 years ago when I got into microcontrollers the first one I 
came across was the PIC lineup. Done some research on them, printed 
out datasheets and such but bought anything for the PICs.

Then I came across the AVRs. Seemed like they were as good or better 
in most cases but both would do the jobs I had in mind. The selling 
point, being a hobbiest price of all the tools, both hardware 
(STK500) and software (AVR Studio, GCCAVR and CodeVisionAVR) are 
better priced. When it came down to it for me the cost of the tools 
made the difference.

Anyone that has an STK500 knows that Atmel is probably only 
recovering the cost of the thing. But what are you going to do? 
Develope things that use AVRs. Where are you going to get the AVRs?

Back in the 70's Apple got a big grip on the developing personal 
computer industry buy practically giving Apples to the schools. Once 
a student got out on their own what computer are they most likely buy?

Of all the personal computer manufactures of the 70's as far as I 
know only Apple is still around. If they are around they are making 
IBM PC compatable computers. What ever happen to Tandy? Screwed their 
customers with almost compatable IBM PCs.
