4150 VS 1940 - Speed

[prototype]

I was quite surprised when I picked up an IPAQ 1940 at the store and saw how fast it was compared to my 5555.

I've been thinking about moving from a 5555 to the 4150 ... but it has the same processor.

Can anyone comment on the speed of the 4150 ... is it zippy like the 1940 is?

thanks
