Is Froyo (android) really so bad?

I'm looking into getting the Samsung Doubletime. It seems just perfect for me, with the size and qwerty and it's WHITE (i've always wanted a white phone) and uggh just perfect. And it comes with a 2 gig sd card free so then storage is COVERED! woop woop.

But it has FroYo OS on it. I know it's a few old, but is it really that bad? I don't really care TOO much about the OS, just as long as the phone isn't gonna be so much worse than Jelly Bean because it's a couple OS's old.

Will FroYo be okay?
