More powerful? Isn't that one a centrino? How much ram? And what kind of battery life do you get? Would you really want to benchmark it against the iPad for web browsing?
Careful there, you could make a fairly stupid error in thinking "centrino" is a processor; it's a platform. This machine has a Pentium M at 1.7 GHz which is quite damned powerful, actually. 1.25GB of RAM since I don't much more, 320GB of storage space.
And yes, I'd put this up against the iPad for browsing any day and twice on a Sunday. Safari, or more accurately Mobile Safari has nothing on Firefox and the vast array of addons/extensions I can use.
As for battery life, well...
this is a real computer and it's 7+ years old. When this tablet came out years past, it was considered to be
revolutionary whereas the iPad is just similar technology that has evolved hence it is
evolutionary. Not the same thing by a longshot.
And before you speak up and tell me I shouldn't be comparing a full blown desktop-class browser with a mobile one, I go back to my original point:
One is a narrow profile device - the iPad - and this is a full blown actual computer with all the various and expected accoutrements.
You can't compare them, and I just proved it.
