Well even if I have to Agree on some parts I am sure he could have said it better and more direct.
The market is waiting for Iphone 5 (if it comes out) in September, well that is if we get stock right away or not like 3 months after the rest of the world
Windows Phone Mango or 7.5 is about to come out with handsets from Nokia and Fujitsu starting to appear in the blogs.
On Android, Google is very close to announce Ice Cream Sandwich also around September and I am sure there is manufacturers with phones ready to go, just waiting for the OS.
But in the same line, when it comes to technology the question is always how long do you have to wait as there is new phones and updates coming out all the time. I would normally say if you can live with your current phone for another six months then yes dont jump strait in, but if the brick is about to exhale its last breath, dont wait.
