According to WPCentral you can get the Nokia Lumia 900 without contract for $449. yes $449 with no strings attached, that's really cheap considering that's the same price the Lumia 800 currently goes for, so does that mean we will see the Lumia 800 drop to somewhere around $349?
The HTC Titan II is said to go for $549 compared to Lumia 900's $449, that's $100 more expensive than the 900
If the Lumia 900 didn't appeal to you, it would now.
Buying an unlocked phone gives you freedom from 2yr contracts, you can change phones without paying a penalty fee, fees that can be quite exorbitant and also with Nokia set to release their "revolutionary" and "unbelievable" windows phones at the end of the year, you wouldn't want to be tied down to ta contract phone now would you, IMO.
