Yes, price/performance was one of my considerations, too. And I also
have the row of navigation keys which are indeed good to have.

Another question ...

I have my laptop running fairly well now with patched with
patch-2.6.20-rt8 and Rui's rtirq script. jack, jack_alsamidi, patchage,
specimen, seq24 work fine along with my usb midi keyboard.

One issue though, I'm getting a nasty zipper noise in one monitor
connected to the edirol ua-25 whenever any keyboard, trackpad, disk or
video activity happens. If I unplug from the power supply and run on
battery the noise goes away. Everything (laptop and 2 active monitors)
are on the same power strip. ua-25 and remote25 are usb powered. I
recall someone else reporting something similar recently.

Is there anything I can try to do to get rid of the noise when plugged
into power?
