Most camera RAW filesystems store between 10 and 14 bits per channel. You are right that compressing PNGs on-camera would be a bottleneck, and that is probably the main reason camera makers stick to RAW.
Compared to JPEG the other main camera format , RAW files have much greater dynamic range, allowing users to adjust exposure and color balance without clipping channels, and to have more available channel information and fidelity for instance, when color-mapping.
RAWs also usually have much less post-processing and noise reduction applied than JPEGs, allowing users to recover more detail. So I would assume that is the primary reason. Even without that limitation, converting the image data especially from a high resolution DSLR to PNG would take a noticeable amount of time on camera hardware. Probably too much time to make allow pictures to be taken in rapid succession. Thanks for reminding me of that, I think my camera saves a jpeg version inside the raw file.
I tested it out with irfanview, and I can finally browse through the images without waiting 10 seconds for the next to load up. It will be less of a pain. Edit: I remember changing something in the raw setting of my camera, for higher resolution jpeg.
There are freely available RAW editors also. The latter provides quick previews while the former preserves image quality. I only shoot in raw, just to maintain the best quality possible.
