I always wait a couple of months before upgrading the OS - but am anxious to get icloud on my work/home machines, so have been wanting to bite on ML, (currently on SL) but the issues listed make it sound like maybe it should be a 2-3 month wait before upgrading, and deal with the fact my mobile Apples will continue to enjoy the cloud, while my stationary ones wait
I like the cloud (using google some now) - I have to access files from all over the place- and it gives me great mobility, and I like it better than carrying around a flash drive from work to home and back again (mostly because I always forget it).
