I'm not a fan of "me too"s, but I've been a DreamHost customer since 2001 and use them for smaller sites and may try VPS and/or dedicated with them in the future. I recall one rough patch with them in 2006 (http://www.dreamhost.com/dreamscape/2006/08/01/anatomy-of-an...), but I felt like they did a pretty good job of keeping customers informed and so I stuck with them.
I've been a DH VPS customer for... years now. Don't even remember how long since I upgraded from shared. (And I've been with DH since 2006.)
Coming from the shared environment, having a VPS is infinitely nicer. We would have an issue every month or two on shared hosting, but now it's an issue every year or so on their VPS knocks on wood
My general experience with DH is that uptime is fantastic... but when it rains, it pours for a day or so. But then right back to clear skies for months.
