Except for the fact that there won't be a huge rush on LTE device release since full implementation isn't until 2013 to 2014. There are about 39 markets slated for initial LTE launch and the rest will phase in slowly. So yeah, trying to sell more expensive LTE devices nationwide for advanced use on a system that won't be fully implemented for a couple more years is a smart marketing move.
Not.
I hope your right, as much as I'm glad LTE is coming I'm always around wifi so having a fast network speed isn't so important. Plus I could do without the extra costs.
