NOTE: This might be old news to some.
I've been checking priododically for LTE in Minneapolis on my EVO LTE, and while it's nice to see it mapped along the highways downtown in Sensorly, the only place I've ever actually gotten it is in my 21st story apartment... which is about a 15 blocks from the nearest purple blob.
Starting last week, I've been getting a steady two-bar signal. I never got WiMax in my building because it's a brutalist-archtected concrete fortress from the 70s, but LTE signal is steady, although as soon as I go down to the lobby, I lose it. Speed ain't bad, but it rarely cracks 10Mbps, instead hovering around 6-9Mbps down, and about the same up. I hope we can expect better once its fully deployed, but it would be fast enough to download all my podcasts on the go, wheras Sprint 3G sucks for that.
Of course, since it's just in my apartment, it can't compete with wifi, so it's mostly just a glimce into the future for now.
