Here's a question for the Mom's with infants,
what bottle do you recommend and why. I was looking at them tonight and things have changed quite a bit since my girls were little, there was even one by a doctor that is supposed to reduce colic.
My DD didn't keep anything from when Brandon was a baby so she will be starting all over again.
The one you're referring to is Dr. Brown's, and my girls have had a decent time with them. The truth is, for 99% of babies any bottle will do -- honestly. If they are preemies or just a pain in the butt with regards to digestion or colic (my girls nailed all 3 categories), she might look into a "specialty" bottle. Essentially, gas comes mostly from 2 places - the gut, which you can't help (except with specialty formula IF it is warranted by a medical diagnosis, otherwise you're wasting your money) and the bottle. The small amount of air "created" by most bottles - even your super cheap, "standard" evenflo or gerber with regular 'ol nipples - doesn't hurt most babies, but some are more sensitive to it.
I hope that made sense, now for my thoughts on the 'specialty' type bottles, both from pediatric nursing and mothering difficult newborns...
Dr. Brown's really are good. They are slightly overrated, in my opinion (as in they aren't necessary for everyone), mostly because they are trendy ... but they definitely create fewer bubbles.
Soothie makes a similar "straw system" bottle that works just as well, but it's harder to find. It's not much cheaper either, so we skipped those (other than the 1 we bought to try).
My favorite overall is Avent (by Phillips). They have a different system, but are just as effective (if not better) at reducing air in the bottle. They are more durable, in my opinion, and require no extra "pieces" like Dr. Brown's.
If you have specific questions, please let me know. In our house we have something along the lines of 60 bottles, ranging through about 8 different styles in addition to "regular old bottles". I thought we'd never find something that worked for my 2, and of course now they're big enough - in the blink of an eye, might I add - that any of them that we have are now fine.
On a similar note, whatever you do don't waste your money on BPA-free or glass. If they happen to be BPA-free fine, but do NOT get sucked in to spending extra money, as many manufacturer's will have you do. The American Academy of Pediatrics, the FDA, the CDC and chemists around the rest of the world have all done studies and have continuing task forces that say that the amounts of BPA in any plastics we use for ourselves or our babies is not harmful. Just my $0.02, but from very educated sources

If it's something you all choose do to for your own convictions that obviously makes perfect sense, and you'll find plenty of options available without BPA... but just take manufacturer recommendations (and media hype) with a grain of salt, you know?
ETA: Elizabeth brought up a good point, and I alluded to it as well, about the Dr. Brown's (or similar soothie) bottles. They do have more pieces to clean, transport, keep track of, etc. That being said, they aren't hard to wash. All of the parts are dishwasher safe and fit nicely in any 'bottle basket', and if someone wanted to wash by hand instead, they come with a little (kind of cute

) brush just for the straw, like a regular bottle brush but the right size.
