Same here, the droid is slowing down... but I just bought it in April 2010... so I still have awhile.
My concerns/questions are:
-battery life
-will my city have LTE up and running? If not, do I still have to pay $50 for 5gb?
-cost- will my work discount apply to the LTE data plans? Is a data limit with increased speeds worth more than unlimited 3G?
-1st gen hardware- I tend to pass this stuff but with Android evolving so fast, I'm sure it won't be more than a few months until Motorola, Samsung, etc. come out with their own 4G hardware. Fascinate 4G? Nexus S 4G? Droid LTE?
This will slow the Verizon iPhone switchers. I firmly believe that the Verizon iPhone will be nothing more than a rewarmed CDMA iPhone 4, which I'll take a pass on.
They're banking on the fact that there is so much pent up demand for the iPhone that people will just hand their money over for one. They're gonna botch this one- I'm guessing LTE iPhone 5 won't happen until next year, and that's 50yrs in the mobile world. They did it with the first iPhone (EDGE -> 3G) and they're gonna do it again. By then Android will have dominated the LTE handset market.
A fast, sexy, LTE, brand new Thunderbolt will make even the most hardcore Apple fan think twice. But the increased data plan costs is a debbie downer, especially since the network isn't entirely rolled out yet.
