I am tempted to go down the Nexus route, even though I do actually like HTC Sense.

I might wait for the next Nexus phone, not that I will be needing a quadcore CPU and whatever else it offers. Hopefully it isn't bigger than the Galaxy Nexus because that is pushing how large I want a phone. I think the HTC Sensation is the ideal size.

Sense 3.6, and I guess 4, have been received quite well. Much improved from the days of Android 2.2. Less bloaty and more functional.

Not sure if there are any launchers that replicate it, but I doubt I'd use one. I'd just get used to stock android. I liked it on my tablet.

Oh how I miss it :((

I have an HTC One S, that came with ICS-y Sense. It's still unredeemable crap. Phone is great, though- and now I'm running Cyanogenmod on it, so all is well.

Well, all will be well when CM updates to Jelly Bean.
