I loved the idea of WiMAX ... but

• until it's deployed in a region I actually spend ANY time in, it's still vaporware, IMO
• until there's more than one nationwide carrier that's using it, I find it difficult to believe in its long term viability ... it's even more of a narrow field than CDMA, basically

For the second one, without regard to the quality and purity of the technology, LTE seems a lot more promising to me. The other 3 nationwide carriers are going with LTE over WiMAX, leaving me to believe that LTE will be more successful and available. But, that's still vaporware. Any WWAN device that gets delivered, before LTE or WiMAX is actually nationwide, needs to be on a WWAN platform that isn't vaporware. And, IMO, that's EDGE+HSPA or 1xRTT+EVDO. That, or a hybrid (like the Russian HTC 4G device which is HSPA+WiMAX), so that real customers can actually use it with existing and legacy infrastructure, and niche and future customers will be able to take full advantage of the WiMAX potential.

WiMAX isn't yet fully baked, and thus the N810WME was poorly conceived, from a product/marketing point of view.
