The ColorMunki delivers some nice profiles, but do remember the market it is aimed at.
If you understand rendering intents and why you might choose to use one to another, then you are in the 'expert' category, not a typical ColorMunki user ;-)
I've (like -everyone- else who has posted comments) only had the latest beta software to test with my CM so I don't really want to make detailed comments on CM profile quality at this stage, other than it produced perfectly acceptable profiles (perceptual RI) for my Epson 1160 and HP K80. Note that I don't use either of these office printers for my fine art prints ;-) (Epson 9600 and 7880)
The CM is firmly aimed at a (big) market, most of whom will have far more of a "that's good enough" attitude to profiling than some here on this list.
I have to keep remembering this for when I'm putting materials together for a longer article than my
initial review Still, not actually selling profiles or having direct business connections with any of the companies I test stuff for really helps keep a bit of perspective ;-)
I do quite a few talks on colour management for local camera clubs and I've long had a quick 'test' I sometimes apply when I'm asked a detailed question by someone wanting to get into their own profiling etc. It's simply "Do you paint behind your radiators?" if they look at me as if the whole concept of not painting all the wall behind a radiator is unthinkable, then I make sure to point out that a key part of colour management is knowing when to stop, when the results meet your needs... As you might guess, I've never been called a perfectionist ;-) :-) and no I don't even know whether all the parts of the walls behind my radiators are painted - the visible bits are.
How does this relate to using the CM? Well, if you are of a more 'exacting' nature then I think the 'simplifications' of the CM would rapidly annoy. In any case I really would suggest waiting to see comparisons from shipping versions of the CM software, from a variety of sources before deciding if it would fit your needs.

PS For my own profiles I can be both lazy and exacting by quickly measuring thousands of patches on an iSis - just because I stop at 'good enough' doesn't mean that they can't be damn fine profiles :-)
