4000's built and shipped, and has little manpower remaining for other items. Simply a guess on my part. The problem with VGA support on the bridgeboard is tied to the basic architecture of the interface design of the Janus system, utilizing "dual-ported" RAM to provide the graphics display. The difference between supporting MONO- and CGA-mode displays is minimal, and CGA is programmed quite simply (and ugly) by most programs. It's not hard to emulate CGA-compatibility. However, VGA systems are a lot more complex, and most programs in the PeeCee world support VGA graphics, not by going through the BIOS, but by banging on the hardware registers directly. This is not the case with CGA, because there really aren't any hardware registers to speak of in CGA systems. Providing hardware register-level emulation is a LOT harder to do, especially when we're talking about a multi-processor system (the 80×86 and the 680×0). In addition, the dual-ported memory of the architecture is limited, and doesn't fit the memory-space requirements of the VGA architecture. Trust me – it is not a trivial problem to solve! Item number 4 – the A1200. Patience! it will be here soon, although quantities may not be as abundent for a while. Again, would you rather Commodore keep things secret until they have enough machines built and stockpiled to meet the initial demand? (I'm not sure on this one myself, but I think I prefer things as they are.) Finally, number 5 – "Marketing". What's that? <grin> Actually, Commodore is doing better in that department, although their focus is still primarily some key target niches rather than the mainstream. I think it's a question of playing to your strengths and trying spend your marketing $$$ in areas where they have the highest chances of reaping benefits. I'm not going to give you flak, as I do understand the feelings. I hope I've added some reason to the emotion. – BobR
