I use VGA so I can use an external monitor switch between the AGA MK2 output and Radeon 9200 output. My 32" HDTV has only one VGA and one HDMI, and lacking both a DVI/HDMI switch, I use VGA. The other way involves using the remote to swith from HDMI to VGA each time I switch between the two. Same problem with the 42" monitor with the 2 DVI inputs, I need to use the remote to go between. HDMI switches are abundant, but I'd prefer a DVI-d switch, much harder to locate (KVM's are quite expensive).
