I just upgraded my laptop from Breezy to Dapper a couple of days ago. I haven't seen any stability issues yet (knock on wood :-)). Dapper is the first distro I've tried that I can use my USB scanner with. Others have recognized it, but it never worked. Also, hibernate works as expected for the first time. Still haven't tried suspend. I've never been able to get X to come back properly after a suspend. It'll be interesting to see if suspend works now. Firefox seems to render pages faster now and the fonts look better. I'm sorry that others aren't having good luck with Dapper, but it's working great for me. Robert
