i agree at both alm and cyber. i will only bother with the free stuff when i go into profesional production line, if i want to just "play play" hobbiest, i will simply buy it, dont violate the service that they have provided. it is meant for them to get profit in the long run. put yourself in their position, what will you feel? how many students that they need to fullfill? they are not education department you know! and as Dave has reported, they are suffering in their business.
and at house, if you cant get the chip for several $, i suggest you drop yourself from the school and find a good job. i remember when i was in U, i worked part time as "waitress" to serve drink in a resort, thats how i get my side income, and i can tell from that, i will be able to afford not just a single chip. doing a project that you have paid for with your own sweat is alot "satifying" than a project that you get for free. just my 2cnts.
sure u can say you can get free easier with microchip, but looking at the recent report on ADC offset, it makes me sick'ier on microchip, i experienced that! on another chip. i'm suspecting they are using cheaper method to produce, thats why they can survive with those free chips, thats the business! and we dont know how dirty it is.
