So the first negative thing is that all Windows Phone Tango all are locked and restriced at 256 MB of Ram as the previous windows phone version was having 5012 MB of Ram. In my personal opinion 256 MB Ram is not enought for a smartphone device. One more negative point is that the third party live tiles will not update automatically so you have to make an update by yourself.

These 256 MB devices will not play the video files over 4 MBps bitrate. This appears to be very severe, but we're likely referring to very low-end gadgets - Enthusiasm will even let manufacturers use 3MP cams (the present lowest is 5MP). We're not sure what that means about the 720p video clip producing that is compulsory for WP mobile phone gadgets right now.

Plus, Microsoft windows Phone Dance will carry some great fantastic upgrades. It will let you import/export associates from your SIM card, offer small grained wandering choices and obtain and upgrade applications instantly through Enthusiasm zune. Dance will also more than twice the number of pre-installed applications and assistance new nations around the world.

The MMS feature has been improved so now you can attach many photo files and also video and sound files at a same time.

As we have told you that the Tango version is having many new improvements but many be some of you guys got disappointed with its negative aspects but over all it will be good to use these devices.
