What to do with this cracked concrete patio?

[Christian Wathne]

Hi Everyone, 

I'm about to start a full rehab on a small rambler. One part of the house I'm unsure of what to do with is this cracked back patio. I know concrete over concrete is a bad idea, but with the low clearance I don't have room to do a wood deck. 

What would you do with this patio? Jackhammer it out and re-pour concrete?  Mortar down some flagstone or other stone? I'm open to any idea...
