The world is bigger than USA and South Korea.

There are many more, and while HSPA+/EDVO is relatively easy and relatively cheap to roll out the prices for subscriptions and coverage of the network is not always good quality. For now, HSPA+ is rolled out in 2009. LTE is rolled out after that, and will require more substantial changes.

Nobody is claiming WiMAX will replace HS*PA* or LTE. They will compliment and compete though, and WiMAX will compete with wired (and WiFi) networks as well. Sometimes, even with satelite or dial-up (esp in rural areas).

Exactly, and the former is much easier in hardware such as netbooks.

The existing WWAN are not always

1) Existing.
2) Competitive price.
3) Allow tethering.
4) Use heavy QoS or restrict ports.
5) Provide decent coverage.
6) Provide decent overbooking and speed.
7) Have flexible subscriptions.
8) Or have a nice AUP.

In some regards the same is true for WAN.

In rural areas, metropoles, development countries, or countries with low quality WAN you have potentional.

And indeed, Clearwire is rolling out WiMAX in Belgium. Given the quality of Belgium broadband I give them quite a chance there!

In rural areas for last mile connection. Metropoles for businesses and because people keep residing there. It also has potentional for vacations (given high roaming of HS*PA).

Some of the frequencies are being licensed right now, in the EU, at least (forced, by directive). If I understood correct, every auction in Netherlands includes frequencies for WCDMA/HSPA _and_ WiMAX. EU has put max on inter-EU phone and SMS, but not data traffic. So there is competition possible there as well.

In the Netherlands in Amsterdam Aerea (WorldMAX) provide competitive priced subscriptions. I could buy a month long WiMAX subscription with good WiMAX speed for a mobile device including monthly subscription or even pre-pay. Without tethering/SIP whining and such. However, you'd need a USB dongle. Compared with data plans in Netherlands this is flexible and competitive although these have 90% coverage. Hence, it really depends on your purpose/goal. I can however assure you many businesses in Amsterdam never leave the A10 ring. If you'd have a repair shop or pizza express you could use WiMAX easily and cheap. Even in the shop (yes, it works inside buildings as well as of now).

So all in all I'm mostly aware of the WiMAX developments around my own regions (I know about deployment in some rural regions as well). If I were to go on vacation I would definately check for WiMAX connectivity. And, unfortunately, would not use a Nokia device for direct connectivity.

For every other entry on the wiki page referred to in top of my post you nor me can express an opinion about simply because we don't know about it. Unless you know more than me; it'd like to get a lot of your references then.
