The future of the Palm OS is Linux.
That statement shouldn’t come as much of a surprise, as PalmSource has
been talking about Linux for more than a year.
This week, however, the company
has made good on its intention to move to Linux, with the announcement of a
new Linux platform destined to become the future of Palm OS.
PalmSource’s move to Linux comes at a time when its hardware partner and
former corporate cousin, Palm Inc., is rolling out devices based on Windows Mobile.
The new Linux-based Palm OS is the fruit of the September acquisition of PalmSource for $324 million by Japanese firm Access. Called the Access Linux Platform (ALP), the OS is more than just Linux, though, and includes a number of additional open source technologies.
Among them is the GIMP ToolKit (GTK+),
which is the open source toolkit behind the popular GNOME user interface.
GStreamer, an open source streaming media framework, and SQLite, an embedded
open source database, are also part of the ALP open stack.
Then there’s the stuff that has traditionally been PalmSource’s
bread and butter. ALP includes PIM, HotSync and Palm Desktop, as well as
PalmSource’s messaging and telephony middleware.
PalmSource is also including the Access NetFront browser on the devices.
“It’s mostly new and is definitely the next evolution or iteration of Palm
OS on Linux,” Albert Chu, vice president of business development at PalmSource, told internetnews.com.
Though Palm OS’s future is Linux, PalmSource is not abandoning its non-
“ALP has a lot of architectural difference from the traditional Palm OS,”
Chu explained. “However, one of the things we have kept to make sure
ecosystems aren’t stranded is an emulation layer, so Palm OS Garnet
applications that are well behaved will run on emulation on ALP.”
In addition to ALP, PalmSource will be rolling out a new application
framework, called MAX, for ALP-based development on Linux devices.
Chu noted that the ALP stack is modular and can be adjusted to meet customer’s
For example, Trolltech, which just this week released Qtopia 4, its latest mobile Linux platform, isn’t necessarily a competitor to ALP, but could
in fact be part of the same deployment.
Trolltech’s Qtopia is based on Qt, which is a competitive open source
graphics library to GTK+ which is the default for ALP.
“If a user wanted to use a specific app from Trolltech, PalmSource could put
it in instead of GTK,” Chu said. “We think we provide value in more than
just one aspect of the stack.”
ALP is also not tied into a particular Linux kernel flavor either, and could
also utilize a MontaVista Linux
kernel as well.
Though ALP is being billed as the next generation of Palm OS, will it in fact
be deployed on Palm hardware? Chu noted that ALP is targeted at all of PalmSource’s existing partners and that Palm is one of its best customers.
Palm and PalmSource are two different companies now with two different
