hmmm... did you guys see the "Pirates of Silicon Valley" movie recently at TNT? it is the "possible" story of Microsoft and Apple companies... there you can see Steve Jobs receiving "for free" the user graphics interface (GUI) from Xerox (including the "mouse interface") what made Bill Gates very nervous (since Bill had only DOS, well, he didn't, but anyway he sold it to IBM...and then went to find out who had it... funny) and magically after few business agreements between Microsoft and Apple, where Microsoft would produce some software to Apple (First MacIntosh), Microsoft should gain access to Apple "windows" to do the job, and then again, magically, Japan Nippon Electric Corporation (NEC) came up with a nice Windows Machine... and it was not Steve who sold to them...and at the movie Bill made that flat face that means "and so what?"...... it means what? That we can not purchase Microsoft Windows anymore because it "could" be pirate too? or even NEC machines? Now... I am totally neutral... , but, suppose I take a Atmel 80 Mips RISC core, costing $1.80 a piece in 100k quantity, build an imbedded package with a PIC code interpreter, seal it in a DIP28 package and sell it as a 100% PIC compatible unit for only $2.30, and as a benefit it still running at 30Mips ... what is it? Piracy? hmmm... Second point... If I write a book about poems... ...yeah, well, but in real I do not copy them from the original authors, but instead I just point their books and pages... my book would be like an index, without a single poem word copied from the authors... people could buy my book because they would have a pointer where to read those poems... is it piracy? ... because I am doing money with other people's work!!! those lines on the floor are not very well traced, isn't?
