I'm used to a system where paging isn't an issue, so I don't notice these things. > I rather doubt Microchip cares much about the .01% of PICs sold that are > bought by hobbiests.

Well, that's also true, that they probably don't care, but they might. After all, look at the exposure they get simply from providing something that can be used for hobby type solutions. Everyone who's done anything with an MCU knows about PICs. And I suspect that Microchip is in favour of lists like this one being up and running, since it sure makes things easier for anyone developing an app for a PIC. I don't think this list would be here if it weren't for the hobbyists. I suspect that the Microchip marketing department is smart enough to see that all the PIC hobbyists are a valuable asset to them. So, no, you're right, I doubt they care about the *profits* from the hobbyists, but I expect that they do care about the exposure and support that said hobbyists provide for their big clients. At least, if *I* were in their position, *I* would. As to free development tools, Motorola did some of that for one of their processors, but what they did was a little bit chincy: they provided a buggy IDE for free, and a much better one for a price. The processor was really nice, but I'd go for the Microchip IDE over that any day. --Brendan -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
