How usable is 1024x768 8 bit?
On my A1200 030/50 it's unusable. I run my Workbench in 1024x768 in 16 colours and it's very responsive, but any increase over that and there's very noticable lag to everything. Waiting for windows to slowly draw themselves on screen takes the fun away from using Workbench.
On another note, although the Indivision is great, it's not the only way to get a flicker-free display from an Amiga these days. I have my A600 plugged into an LCD TV using the new S-Video adapter from AmigaManiac.com, which gives me a rock solid display in resolutions up to 1364x536 widescreen. Here's a photo of Workbench playing some music -
