The point about Photoshop not supporting paletted transparent PNGs was new to me.
I only use Photoshop, so I actually believed that alpha channels were only available for 24-bit PNGs.
I wonder if Photoshop has planned future support for paletted, 8-bit alpha channel PNGs?
I wouldn't expect it too much. Photoshop also had a generally dreadful support for PNG (it would compress them very, very badly, sometimes to twice or thrice the size needed) before ~CS3.
