Access Co’s Garnet VM offers people who dislike smartphones a PDAesque experience on a Nokia Nxxx web tablet. It has actually done this for some time, and was met with general happiness.
The product has now been updated to “beta 5″ – while still not final, Access claims compatibility with more than 80% of Palm OS applications currently on the market.

P.S. According to various sources, the N900 is not supported currently.

This works fine on the N900 but you have to download the .deb to the device, run sudo gainroot (install the rootsh package if you haven’t done so yet) then install it via dpkg –install garnet-vm_1.0.4b_ITOS2008_armel.deb.
One possible catch… I did this two days ago and I don’t know if that was before or after this “beta 5″ package was released. I doubt they would have broken N900 support between the last release and this one though… I’ll post an update once I’ve tried this new version (sadly not for a few days since I left the N900 at work).
Turns out “beta 5″ has been available for some time now so it is the version I’m running on my N900. May not be supported but it certainly works.
The most important key combo to learn is Ctrl + Backspace because Garnet VM doesn’t have a mechanism to leave full screen mode and unless you do that you can’t close it.
Oh and coming from a Treo 650 I find it a bit crap that I have to waste precious vertical screen real-estate on a graffiti area I’m not going to use while in landscape orientation. It’s not a problem in portrait due to the long screen but then the keyboard hangs out the side and I like having a keyboard.
Hi,
thanks for talking back!
I don’t have such a box, so I can’t say much!
All the best
