In my opinion it is unreasonable to not go PCIe. AGP is absolutely dead. Old PCI is pretty much obsolete and nearing "dead". Unless someone has a large contract to service what represents a lot of $$, sanity suggests PCIe. Now if I have missed some industrial segment that uses something that "most of us" would consider odd, please correct me.
What I am saying is simple enough, follow the potential money trail. If it is a dead end...just don't. I am not some western pig capitalist, just a guy who tries to see things in a reality slanted light. People need to eat right? By this I mean engineers, and driver / firmware programmers etc... Making the actual functioning board is not free either. I would love to be able to buy a computer with an open-hardware SoC for my personal general purpose computing needs! I think a lot of people could be convinced it is a good idea if the right approach were used. Tap the Android Marketplace. Tap the linux userland software base. Set up a "foundation" or join one and get comprehensive about correcting linux software stack shortcomings. Make it so where people can have a MUCH more powerful "desktop / laptop" that can 100% interface with their shiny new Android Phone.
