I have an android phone.. and I have to say – I am happy with it. But I am not 100% on it.
There are some crummy apps, but once you get a good bunch of them – the experience does increase.
I have a HTC desire HD – it chews battery, but thats because it has a big screen.
I sometimes wish I had my blackberry back, because i used the chat feature quite a lot to keep in touch with friends.
