Well, it's making a serious impact on performance for camera. I wasn't able to reliably download images at even half speed. I gave up and dropped from 115K to 9.6K. I can probably get better speed than that, but even if it's 28K, that's noticable :-(. On the other hand, that's the only real problem I've seen. Unfortunately, I haven't used the thing since the hardware was cutover from -stable, so I can't pin it down either.
