I understand scrolling is a CPU/memory intensive function. The X-fi 2 is a PMP, not a micro PC. Smooth scrolling may be beyond the capabilities of the CPU and memory in the X-fi2.
Scrolling is laggy on the X-fi2. Try scrolling with your finger tip just to the right of the album tiltes. Scrolling will still be laggy, but at least you will not make an unintended album selection.
Laggy scrolling aside, I'm still very pleased with the X-fi 2. The unit has excellent sound quality, a very good LCD display, and a good price for all that you get. I paid a lot less for my 16 gb X-fi 2 then I did a few years ago for my 4 gb Zen V plus. The only thing I like better about the Zen V plus is that it came with a lanyard so that you could wear it around your neck.
