Hoshbo,
I'm a happy 7250 user, but if I were buying new, I would certainly go with the 8703e. There are significant improvements in the newer device. For me, the dedicated phone buttons and speaker option would be worth the $100 difference.
Having said that, I won't upgrade until I can get the discount price because I do like my 7250 very much and upgrading while still in contract would be significantly more exepensive than $100 for me.
The 7250 is a great phone, but there is a reason that they're giving them away right now. The reason is because the 8703e is a better option for most new purchasers.
