Hiho,
looks like the Plucker guys have updated their comparison matrix and now also include iSilo.
http://www.plkr.org/a-vs-p.html
Interestingly, a lot of times they compare a "will-be" version of Plucker (which still contains a log of bugs from what I read at
http://bugs.plkr.org/view_all_bug_page.php) to Avantgo and iSilo, and not a "is" version.
Also they fail to compare the
useability between the products. So instead of just counting up how many fonts which app supports, they should have also mentioned how fast the screen is refreshed, how smooth scrolling works, how fast a document is loaded, etc.
I keep an up-to-date cvs version of Plucker on my Tungsten, only to see how it evolves. But currently I see absolute no reason why I should switch from my rock-stable iSilo to a not-so-stable Plucker.
