All I'm going to say is, I bought a Touch and kept my old phone.
Then 3 months later I ended up buying an iPhone.
I did the exact same, basically the Touch has only wifi and to me while out and about it was bascially a exepensive ipod and served no real purpose, I wanted and ipod + wanted to go on the Internet wherever and whenever I wanted

I'm so glad I got an iPhone in the end
