iPhone 4 v Dell Streak

I am currently torn between the new iPhone4 ( i cant get it for a while due to restrictions for o2 staff) and the Dell streak.  I really like the size of the streak for most of the things I use my current iphone for.  Browsing, email, media consumption, blogging, all seem very appealing to me on the streak.  I love that Android re renders zoomed text to fit the screen, and the layout of the streak and the social integration, but, I am not keen on android 1.6 and its limitations, and I don't like the keyboard with the number pad! Who's idea was this, we should at least have an option to turn it off.  I have sorted a few issues for customers in store, and really enjoy using the streak, so much so that I now think a 5inch Iphone would be awesome!  I really don't know what to do, and I cant justify both!  I installed Fring on the demo streak in the shop, and had a video call with an iPhone4, worked pretty well, although the iPhone4 was in a pretty poor area.
