I agree, those videos show a clear difference in scrolling and general rendering speed between the two devices.

However, it's a mistake to dwell on this even though it's going to be a big part of the "feel" of the device for new users.

It looks to me like a software problem, not a hardware problem. And not an especially hard software problem either.

The browser scrolling - and crash - will be fixed, one way or another. Either by updates, or replacement with another browser, and there are several other browser groups eager to please so there's a healthy competition to do a good job.

That's a key difference from the iPhone. You can count on healthy competition among browser people keen to impress, to try and get the most out of the hardware in time.

You may find that's a big part of the different philosophy between this phone and the others. This one can expect continuous improvement once it's released, independent of what Nokia does. Especially in areas that lots of users care about. The others are at the whim of their parent company.

So, expect it a bit like desktop Linux distros operate: imperfect in many areas that you can see, but expect to enjoy the pleasure of regular improvements without having to pay for them.

That is totally due to the community and open sourceness.

Once you (or any user) "gets" the difference in philosophy, you may find yourself dwelling less on specific but superficial irritations (the scrolling doesn't stop you using it), focusing less on the "what can it do out of the box", and more interested in what it's going to do when a lot of people get up to speed seriously developing stuff for it. Unlike the other devices, this community and Nokia's seemingly good relationship with it means we can improve more of the "core" user experience that we're allowed to on other devices.

Let's move on from scrolling: The browser is quite capable as browsers go on a phone, isn't it?
