I'm running CM10.1.3 stable on my two little boys Nook HDs and the whole CM experience is just perfect on a tablet!
[highly recommended tablet for those on a tight budget by the way, amazing screen resolution and brilliant performance - even for gaming (Real Racing 3/Asphalt 8 for example run absolutely flawlessly!) I made the mistake of getting the 4GB versions though and they do fill up REALLY fast lol]
Anyway, I digress - I do have to give a big fat +1 for Temasek CM11 on both mine and my partners S3s!
For those that don't know, Temasek's ROM is a whole lot more than the basic CM11 - it incorporates all the good bits from ROM's such as CrDroid, SlimROM, NeatROM, CM itself obviously, AOKP etc and pulls the best features all into one place so it's WAY more feature rich and customizable than standard CM11 (which isn't exactly limiting all the same!)
Now, Temasek's XDA thread has been closed at his request (too many users bombarding him with useless bug reports without providing anything for him to work with... been an ongoing problem and he's just had enough of it) but he is still working on his ROM and updating frequently so add him on Twitter (@Temasek71) to keep up with updates directly or just keep an eye on his hopto.org folder

We're currently on v57 but it is a little lacking in features when compared to v50 as CM changed the way they implement some features (mainly multi-sim support) which caused some problems with the way he had ported some features - we're getting them all back slowly and it is well worth the wait as v52 onwards have been super smooth - the latest version v57 has the most recent CM merge of Android 4.4.2_r2 KVT49L which (to me at least) feels a lot more responsive than previous versions.
For those of you thinking of trying CM11 out, go give Temasek's version a bash, it's well worth a try!
