A Lunchtraydeluxe (17-inch PBG4).

Supported models include aluminum PowerBooks introduced from 2003 to 2004 as well as all G4 iBooks.</SPAN></FONT></DIV></BLOCKQUOTE><DIV><BR class="khtml-block-placeholder"></DIV>It's especially nice since I figured out how to two-finger scroll properly after reading the MacOSXHint about it. I was so used to fn-trackpad with uControl that I was using both hands to do the scrolling with iScroll2, resulting in very rough and unpredictable scrolling behavior (holding finger down from left hand and sliding up/down with finger from right hand).<DIV><BR class="khtml-block-placeholder"></DIV><DIV>Peter<BR><DIV><BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 13.0px Helvetica">A little computer haiku:</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 13.0px Helvetica">I can't remember<SPAN class="Apple-converted-space"> </SPAN></FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 13.0px Helvetica">the last time I restarted</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 13.0px Helvetica">I love OS X</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 13.0px Helvetica; min-height: 16.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 13.0px Helvetica">This message sent with Mail.app 2.0.1 on Mac OS X 10.4.1</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="4" style="font: 13.0px Helvetica"><A href="mailto:pkrug@mac.com">pkrug@mac.com</A></FONT></P> <BR class="Apple-interchange-newline"> </DIV><BR></DIV></DIV></BODY></HTML>
