Talking Verizon EVDO here.
I typically get my best speeds from the Washington DC server with NYC second to them. When I was in Las Vegas, it was Salt Lake City with 1.3 Mb down and 128kbs up. Tonight, I'm in Miami and I tested washington DC and it's down to 856kbs. I do better in Jacksonville from home.
While bragging on our cable connections from home is fine, fact is anything above 1.5 MB is usually plenty for one user. I'm much more interested in hearing from other road warriors with different mobile services around the country. Today, this is the real challenge, what you get while traveling.
Also, I'd be interested in what people are getting with their hotel wifi connections. Seems many hotels are hip to wifi these days but as Scott discovered, even a fine hotel like the Luxor went crawling during busy times. For me, my independent Verizon EVDO never suffered in Vegas during CES. I watched fine sling box and a security camera simultaneously while surfing the web. Verizon did a great job in Vegas for CES week! IT's worth the higher rates they charge.
