In short a kitchen lets you choose what you want built into your rom, makes it very customized. But read through the upgrade forums on whats involved, there are some risks involved, but there are quite a few benefits to it as well. I would suggest you use the phone for at least a couple of weeks before even thinking about flashing a custom rom, after all, if the phone works as you need it to why change anything.

But read through the forums and always use the search feature, almost any question you have has been asked (several times) and answered.
