Phones like touch diamond on Sprint Sero plans

[EyeB]

I'm on the Sero plan so if anyone knows of another phone like the htc touch diamond, let me know so I can look into it. I'm just not aware of another phone.

Recently I've been thinking about trading my touch pro for a touch diamond. Is there any reasons I shouldn't? I mean besides the keyboard and sd card, what benefits does touch pro have over touch diamond? I'm thinking this because it turns out I almost never use the physical keyboard so I'm find with the virtual keyboard. I'm only using about 1-1.5 gb of memory so the 4gb on touch diamond seems like enough.

I'm just asking because everywhere I look, seems like the touch diamond is being sold for more than the touch pro so I'm wondering if this is because the diamond has something that the pro doesn't to account for the price difference.

edit: sorry if this is in wrong place, but seemed like phone comparison fit best in trying to find a phone without actually knowing what phone is

PS: It's likely I'll grab a touch pro2 if I see one cheap but I'd like to use a keyboardless phone if possible due to thinner size and I wont keep turning it on when I bump into something and nudge the keyboard
