Yes.. some interesting thoughts there, MIPS in my pocket: hell yeah.
The crazy thing is, SGI did have internal research projects to do such things .. they had engineers working on porting Netscape to the N64, which could very well have served as the basis for a more interesting consumer-end mass market device. Imagine if someone at SGI had put a cell modem in the mix somehow, yikes.
Well, its all a dream. Meanwhile I still have all my SGI gear, and I'm not afraid to admit I've been looking at 3DFX Voodoo cards on EBay a little more than I should have today ..
