wowa on "Iphone or Android phone"

Dh and I have our 11 year anvi. this thur. and we are thinking about getting new phones for each other but would love some advice. Both are phones are over 3 years old and we are with At&t but under no contract. Dd is 5 and almost out of Kindergarden so I have spent alot of time this year waiting in lines to pick her up or waiting at dance class, so I thought it would be really nice to be able to check email or get on facebook while I am waiting. Dh would also like to check email and surff the web some. Dh is not very patient when it comes to phones and computers so I need to find something that is easy to use and would love some advice.
So I have heard sprint carries some android phones like HTC Hero with GOOGLe or Samsung Meoment with Google and that you can get one internet plan to cover both phones unlike with At&t where we have to each pay $30 a month. We can afford the $60 a month I just want to make sure it is really worth it. Dh and I keep our phones for a while so I am just trying to get us the best phones.
Thanks for any info you have,
Kristy
