Personally, I wouldn't use this seat (or any convertible seat) for a newborn, b/c most really don't fit a newborn, no matter what the minimum weight says. The bottom slots on this seat and Britax are 10" vs. the bottom slots on most infant seats are 5-8". The shoulder harness needs to be at or below the top of the shoulders when a carseat is used rearfacing. Now, I know that since the convertible carseat is taller, the newborn "riding up" in the carseat during an accident isn't going to hit his/her head on anything b/c there' so much shell above his head, but he's safer the less he moves, period, which would only happen in a seat where the harness slots can be at or below his shoulders. Also, infant seats are generally a bit easier to get at the correct angle, whereas convertible seats like this one may be too tall to easily get installed at a 45 degree angle.
Even with all of the infant padding in our Britax Decathlon, our ds still didn't fit in it unti he was around 12-15 lbs.
I'd suggest buying a Graco Safe Seat 1 b/c it will last the longest of all the infant seats and it's a great seat! Most infants don't outgrow it until they are 12-18 mos old, depending on how big they are. By then, all of these new higher weight carseats will have been on the market awhile, prices may be down, bugs will have been worked out, etc. etc. And if a $200+ carseat is still not in the works, at least the Evenflo Triumph Advance will still be $130.

Otherwise, the Como sounds great!
