Unfortunately, it's just been confirmed Sharp entirely drops the Zaurus (tiny, Linux-based, clamshell, REALLY excellent PDA's) line. No comparable successor is known. This is indeed a sad day for all Linux / Unix fans - the Zaurus really rocks.

See this OEF thread for more info.

Linux undoubtedly has its place on mobile devices under the sun. Now that I’m planning a new roundup of all “let’s remote control your desktop PC from your Pocket PC” solutions, I’ve also thoroughly tested the well-known Linux-based rdesktop on my Sharp Zaurus C-760 (running under pdaXrom, the native (!) X-Window environment for Sharp Zaurii; its non-pdaXrom-based versions are qtrdesktop (Cacko and the original Sharp ROM) and Opie-rdesktop for OZ/OPIE; also see this for more info) and found it immensely better and more feature-rich than most other (even commercial – see for example Mocha’s Remote Desktop client) Pocket PC- or Palm OS-based remote desktop solutions. And the list doesn’t end in here: you can run for example Kismet on most Linux-based, Wi-Fi enabled devices (like the Zaurii with a Wi-Fi card).

Now, all major “gadget” manufacturers have announced Linux-based mobile devices. They are as follows (I really recommend checking out the links!):

Many hi-end gadget freaks know what Sharp Zaurus is – a really decent, Linux-based device with an astonishingly (it can directly compete with the Sony LCD screens used in the, screen quality-wise, best VGA Pocket PC devices like the HP iPAQ hx4700, all Fujitsu-Siemens models and the HTC Universal) good screen.

Yeah, I just can’t stop buying toys... I mean PDA’s :)

Just bought a Linux-based Zaurus SL C-760 (see for example this, this and this reviews).

This doesn’t mean I’ll abandon Windows Mobile, not in the least.
