Lost in the history of the calculator-PDA for Linux

The Qonos Scientific PDA calculator (this is exactly what this thing is called) was developed by Hydrix , whose founders had previously worked for HP.

As the name implies, this calculator works under Linux.

But after 2005 there is no news of him.
The photo placed above the habrakat is just a render of the CAD model of the prototype.
However, in 2004, Jean Yves, one of the founders of Hydrix, outlined the following characteristics of the model:

operating system

• eCos - works under 512kb SRAM and provides a month of work without recharging.
• Actually Linux (apparently no name) - works under 64kb SRAM and provides one day of autonomous existence.

Soft

• Emulation calculators hp49g and TI-89
  
• Mathematical software - GNUPot , Giac / Xcas , MathsExplorer
• Standard for PDA programs - calendar, notes, tasks, schedule, calculator

CPU

• Intel PXA 263 XScale processor operating at 400 MHz
• 32 MB on a flash memory chip
• 32-bit data bus

Screen

• Shades of gray, 3 '', 320x240
  
  
  
• Color screen support was promised later.

.

The rest of the iron

• Mono speaker and microphone
• Stereo audio input and output ports
• Keyboard with tactile feedback (whether it vibrates?), Designed for quick and accurate data entry
• Compact Flash Type II slot

Here in 2005 a message was published, which said that the date of the unit’s release was postponed to October, and since then this calculator has not been heard.

And in principle, I wonder, would I use such a calculator? The thing is certainly interesting, but personally I would prefer an ordinary emulator science.
Maybe that's why it did not come out?
