I use my Dinovo Mini almost Daily. My bedroom TV is hooked up to my Dell Studio Mini. I watch a lot of shows on Hulu or torrents. Dinovo mini was the best option to use as a remote. It wasn't cheap but was worth it. Note, I use the dongle not bluetooth.

To sum up the experience: battery life is great, i probably charge it up overnight every 2 months. I dont think i ever had a connectivity issue. ( i have heard using bluetooth and not the dongle has connection issues). I love the built in Media Center switch, that works nicely. Great javing a keyboard, and can basically do anything that would normally require keyboard/mouse. Only negative is the built in trackpad/mouse needs major improvement.

I have never used it with PS3 so no comments on that. It's not for daily computing use, but for HTPC and Media Center use i love it.
