What kinks are you thinking of?
What can be said, at the moment, is that, for most users, by far, the system works and is reliable but as I said to Reaper, you don't need to rush. You still have 7 months or so. If you are not in a hurry, I'd say that you still wait like 3-4 months and MS should have improved Windows 10 again.
Now, if we go a bit more into the details...
First, after installing, IMHO you must consider the privacy issues with the defaults settings and change them (unless you don't care at all about various data being collected and also possibly shared with "trusted third parties" you don't know). No need to get paranoid either. See my answer to reaper about how to deal with that easily.
Some people report issues, inevitably, like slowness or some things not working anymore as always with a new system.
Also, the new browser coming with Windows 10, Edge, will perhaps be great in the future but, for the time being, you can forget it unless your needs are very basic (and, once again, mind privacy settings).
You can get Firefox (which is now also available in a 64 bits Windows version but only on the FTP server of Mozilla.org, not yet on the public download page; it should be by the end of the year). Or Google Chrome (privacy to set correctly!), or some other like Opera.
On the other hand, keep in mind that the Windows Media Center doesn't exist anymore in Windows 10 and if you used it, you will need an equivalent free or paid. (There is no exact equivalent though.)
You can get the free, open-source VLC to play almost any media and many streamed sources (it will not play all Blu-Rays though due to possible DRM copy protections that are incompatible with open-source software, and you'll need a specific Blu-Ray player, paid, if you hit this issue.)

VLC is not pretty because it's made to use skins that totally transform it, here

Also, the interface structure is not always friendly (and sometimes awkward TBH if you need to go deep into some features) and some users dislike it. In this case, you have several alternatives, not necessarily as powerful. Like SMPlayer, DiVx,...
