Yes, the UI hasn't changed that much for a while. But that's the reason why it's so good. Why change a good thing when the formula works so well. One word that is synonymous with SE, and I think that most SE users would agree, is 'unassuming'. You see some current SE users come from Motorolas, Samsungs, LGs, Siemens, and the like, and they actually appreciate the how well the UI of SE works when compared to others. The only other UI that is comparable to SE is Nokia S40. But even with the S40s, they are a bit underpowered to the S60 smartphones. SE UI is really versatile, and you can run multiple apps at one time. For me, I'd keep it the way it is with SE doing minor improvements on upcoming phones.

But it's been around for a long time now, hasn't it?

Why? It's pretty fast for my W300i, it's, overall, pretty fast, and, somewhat, more entertaining, and streamlined that the kyocera oystr and Motorola Pebl. But then, I never really like Motorolas

The User Interface has been around for around 2 years now, and I see it still being used in the S500, W580 and the T650. Is it sitll going to be used on the W960, K850, K770 phones???

What are some improvements you would like to be made to the present user interface?

I think they should keep it and add some minor details to it, and also increase the time reaching files and overall, being more faster. The user interface is getting old, and needs to be changed.
