FTM: opinions on car seat/stroller combo

AC • ?
Okay, so this is my first baby. I'm having a girl. I seen te cutest car seat/stroller combo. My question to all you other moms out there is... 
Do you think it's better to get the combo or just worry about the car seat for now and get a stroller later on? I'm due July 19 and I live in Ohio. Lol (not that it really matters, then again...) 
Thanks ladies!
