VZ will make a bad strategy if they delay to 2/24
If they are considering the iphone 14 days return period and delay the thunderbolt to 2/24, then they will just face more serious competitors in android market.
First of all, people who are eager to get the thunderbolt are most likely not getting the iphone. It is a non-sense thinking to worry about the iphone 14 days return period.
Second, T-Mobile will get their samsung Galaxy S 4G on Feb, Sprint will get their Kyocera dual screen android soon, and AT&T will get their Motorola Atrix 4G most likely on 3/6 (And atrix is more highly expected by people than TB, TB will lose its marketing advantage for sure!).
Which means, if VZ released their TB on 2/24, then they will lost their advance in Android 4G market due to the "not so special" specs of TB. I believed other 4G phone will get more attention than TB during the 2/24 period.
If VZ does release the TB on 2/24, then they will get higher return rate on TB. (I can buy the TB on 2/24, then return it on 3/6 to get a Atrix! )
