[Q] Droid RAZR MAXX HD + Lapdock 500 - Does it work OK, and if so, which ROM is best? topic

Hi. I've searched around the forum a bit, but most topics about this seem pretty old, so would like to know the "current" status please?

Some background: I currently own an Atrix 4G MB860 and lapdock, and while not perfect, it works great, saving carrying around my laptop or tablet to get a bigger screen experience for web browsing, movies, etc, as well as much faster typing for e-mails and stuff.

I've looked into it, and as far as I can tell the Droid RAZR HD is the last/best Moto phone to support a lapdock (correct me if this is wrong!) as older phones have the lower spec's and low screen rez, while newer phones dropped HDMI (another bad idea, as I still hook my Atrix up to the TV to show photo's, etc)

So, am I mad to go from Atrix to RAZR HD (pref MAXX for extra storage and capacity) - has anyone else upgraded like this, and so can give me some comparisons?
Should I forget it and go to Moto-X, etc, and just forget the lapdock idea?
Who has it working nicely, and with which ROM(s)?
What does work and what is so bad you want to throw it out of the window?!

Thanks in advance! Kev
