What I find interesting in WiMax is the possibility that this technology may force Mobile operators to move from the cashcow model to a flat rate model, unlimited access that exists in most countries for fixed broadband. In the end, WiMax may lead to a radical change in Mobile market. Sprint has already indicated that they are planning to do something in these lines.
A interesting market to watch is Korea where a Wimax (Wibro) like network is changing the rules of the game.
Here is a (probably incomplete) list of WiMAX networks planned, being rolled out, or already rolled out: http://en.wikipedia.org/wiki/List_of...WiMAX_networks
The nice thing of WiMAX is that it, like all previous <= 4G, has roaming support which WiFi doesn't. WiFi also has a short range. Although WiMAX has a far better range, the speeds go dramatically lower if you're not near the AP. WiFi has this too, and 3G too, but with 3G there are simply a lot of APs. In one way WiMAX is the very same as 3G: the frequencies are sold to corporations who bid on these frequencies. So, with WiMAX too, you have a monopoly situation. WiMAX won't solve this problem, but it might allow corporations to compete with telcos leading to advancement in this industry. Telcos roll out WiMAX in rural areas, and not in areas where there is already connectivity. Non-telcos do roll WiMAX, to compete with telcos.
In theory, telcos could roll out WiMAX and allow users to use this with data plans and so on. But telcos want to 1) get their 3G investments back 2) limit data usage for that (either not good enough embedded device, or no tethering) 3) limit the usage of wireless 24/7 Internet connecticity so they can still earn money on their <= 3G networks. VPNs, VoIP, and tethering are often illegal by contract. The reason for this is point 2 and 3.
Unfortunately, my bottom line is, for a mobile device non 24/7 connectivity simply doesn't cut it. Say you use your NIT as a navigation system. You'd want to have accurate, recent data about e.g. traffic. You don't drive to McDonalds to use their WiFi AP to update this information. That is way too begin 90s (here it was called Greenpoint).

I think I'll wait for the next next tablet
I'm moving to rural Missouri soon. No WiMax there I'm sure.

I'm just still curious as to why Nokia seems to think Wi-Max is more important then wireless Gigabit/N especially since the draft is now off of N.
As many ppl have pointed out that Wi-Max starts off on shaky ground and only a select few markets whereas many ppl have or would or could upgrade to Gigabit.
The point of Wi-Max isn't exceeding the speed limits of the devices' existing links, but rather giving the device greater range for "ubiquitous" connectivity to the internet.
If my area had Wi-Max, I'd be all over it, assuming the rates were reasonable. (Ha ha.)

In theory, this is a good thing for rural areas, but its also good for big cities where a large number of potential customers have 24/7 coverage in the city.

Unfortunately, telcos don't want to invest in a competitor for their rolled out 3G network, they don't want faster speed for their customers, they don't want to see customers as people who might have something interesting to share hence they prefer techniques who have limited upload speed (WiMAX is symmetric in this regard), and they certainly don't want customers to use things like VoIP. Too bad for them because sooner or later it will happen. The only question is when (and aspects like is the latency is adequate enough for general usage).

Another good thing is no contracts and highly tailored plans like being charged by the hour/day.

There's no way the N8x0 could support the added power requirement for this radio solution. I will have to look at the current proposed n draft and some current radios to see what the implementation is.
Correct me if im worng, but the main point of N is MIMO
which, by definition, requires more than one input and more than one output
or is it that the single antennas are sending and recieving on two seperate channels?
and what mobile Ns have you seen?

in that case id really like to know what Master of Gizmo was suggesting in his last post about "mobile 11n" and the 1x1 parts

Unlimited data plan can be WiMAX-based provided its rolled out.

Interesting (AT&T & WiMax):
AT&T: WiMax Is Top Candidate for Rural Broadband
http://www.unstrung.com/document.asp?doc_id=160620
AT&T Inc. (NYSE: T - message board) is considering expanding its WiMax footprint beyond the frozen wastes of Alaska as the rising cost of copper starts to make DSL deployments prohibitively expensive in rural areas of the U.S.
The carrier's CTO, John Donovan, tells USA Today that WiMax is “at the top of the list” as an alternative technology to copper for the operator. He added that the carrier is also considering cellular femtocells -- tiny base stations that extend the speed and coverage of wireless signals in the home -- as the way to get cheaper broadband faster to country folk.
