This has been gone over and over for the past 6 months. There are pluses AND minuses for going 3G.
Battery drain.
Cost of parts.
Lawsuit that stopped some 3g chips from coming into the country.
Battery drain.
Coverage (I live in an realtively alfuent dream apple demographic of L.A. and 3G does not cover us.)
Miniaturization of parts.
Battery drain.
It will get here soon, if it is a big problem for you wait till Jan. and buy Rev B.
1) Battery drain: Insignificant and mostly depends on the phone itself, NOT the chip (but regardless, I'd rather take a possible "battery drain" over a lack of WiFi coverage and an "excruciatingly slow" EDGE network).
2) Motorola RAZR has 3G chips, as do many phones, without any "added costs" (the new 3G RAZR is going for $49.99 on ATT with rebates).
3) That lawsuit didn't come into fruition and the judge didn't order Qualcomm to stop distributing 3G chips until a few weeks ago, if that, long after Apple began iPhone development.
4) Battery drain (again? that was number 1, perhaps you're losing points?

)
5) Funny, my friends in LA who work in high stress jobs that require constant use of their smart phones, etc. use 3G in just about every area (on Cingular/ATT and Sprint), no problems. Where is this "area"? Bakersfield, CA? lol
6) Miniaturization of parts? What? Seriously? If they can fit a 3G chip into a RAZR or KRZR I'm sure there wouldn't be an issue with working one into an iPhone.
7) battery drain? LOL If you're trying to be sarcastic, your battery drain point is erroneous. Again, I have a RAZR 3G and I use the web on it for a few hours a day, no issue. I'm certain with the combination of WiFi AND 3G, as well as improved battery performance, the iPhones demands of high bandwidth would be easily met without taxing the battery (and besides, are you surfing the web in your sleep? let's be realistic about how much battery usage is necessary).
So, sorry, those arguments don't hold much weight. Unless Jobs had Ms. Cleo tell him a judge will order Qualcomm and other 3G chip manufacturers to halt 3G production, there really isn't a reason why Apple neglected its usage (and the lawsuit filed in May 2005 doesn't necessarily mean a judge will order a halt in 3G production in the near future, if that were the case then ALL other phone manufacturers would have compensated for such and implemented WiFi over 3G, which isn't the case).
