PC World had a good little article on this and here is the meat:
"Verizon says it will sell the 700p "within the next few weeks" for $400 with the purchase of any voice/data plan. Sprint (which says the 700p will be in its stores by the end of the month) is asking $550 with the purchase of a one-year plan, $500 if you commit to a two-year contract. Sprint will sweeten the deal for those who sign up for two years with a $100 service credit, but you only get the credit when you activate the phone, and you still have to pony up the $500 up front. However Verizon does not appear to offer a one-year option; its voice-data bundles require a two-year commitment.
Verizon's cheapest voice and data plan cost $80 a month for 450 minutes of voice calls (with unlimited calls to other Verizon Wireless phones) and unlimited data. Alternatively, you can forgo voice call service and pay $45 a month to use the Treo 700p for unlimited data only.
To use the 700p as a wireless modem (connected to a PC by either USB cable or Bluetooth), you must add an additional $15 a month if you've got a voice and data plan, $30 a month if you only have the $45 data-only plan. Those fees would bring your monthly tab to $95 for voice, data, and wireless modem services on Verizon Wireless, or $75 if you don't want any voice service
Sprint can beat Verizon on monthly charges if you get Sprint's cheapest voice plan ($30 a month for 200 minutes of talk time), its cheapest Power Vision pack ($15 for unlimited data and a little bit of TV service) and the current promotional offer of unlimited Phone-as-Modem service for $40 a month. That comes to $85 a month."

The high DUN charges clearly show, to me, why Palm left out, or was required to leave out, WiFi. The carriers, I'm sure, didn't want anything that could subsititute for this fee-based service.
I'm currently on Sprint and even though I'm only about 40 miles from New York City I can't get EVDO service here, according to Sprint's map. EVDO is, as a matter of fact, pretty limited in both Verizon and Sprint at the current time. I saw a great chart recently on the Web showing a comparison of the EVDO cities with both Verizon and Sprint, but I've forgotten where it was. My memory is that the coverage was very limited for both carriers and both of them covered about the same number of cities. If I can find it again I'll post it here.
Given this situation there is nothing that would make me want to switch from my 650 to a 700. I'll be looking at the 700w when my plan runs out or I might move over to Cingular so that I can get GSM and then tap into the great number of phones that are available in Europe. I must say that the Nokia 9300 seems very interesting, or one of the new HP units with built-in GPS.
Something that really made me have second thoughts about GSM was a business trip my wife took to London last month. She has a Cingular GSM Treo and whenever I dialed her number here in the States I got her immediately in London. If I hadn't known she was on a trip I would never have realized she was overseas.
