Back in March, I tried to find as many Linux-based UMPCs as I could. At the time, I found 18, which was expanded to 20 with the help of commenters. After many more Linux-based UMPC releases, I decided to see how many more I could find. The first 20 on the list below are from the previous list.

1. Eee PC
2. CloudBook
3. OLPC
4. Noahpad
5. HP 2133
6. Elonex One
7. Gecko Laptop
8. Intel’s MID(s) – Yeah, yeah, I know it is a “MID” not a “UMPC.” Who really cares?
9. BPETD H9
10. EB MIMD
11. eo TufTab v7112XT
12. Pepper Pad
13. Lime PC
14. Simple PC
15. ECS G10IL
16. WING
17. Unnamed Acer UMPC – Linux on this device is not confirmed, but quite possible It is now called the Aspire One and it does run Linux.
    
18. Gigabyte M528 MID
19. Nokia N810, N800, N770
20. Zaurus
21. Bestlink Alpha 400
22. MSI Wind
23. Aware A-Pad
24. 3K RazorBook
25. Sylvania G
26. Gigabyte M912V
27. Unnamed GeCube

31. Lenovo IdeaPad S10
32. Dell E
33. Gdium
34. Elonex Webbook
35. Pandora

Wow! 32 32+ Linux-based UMPCs! Here is my question: many people, including myself, consider the Eee PC to be the product that caused so many new UMPCs to appear. Sort of like a spark for the UMPC business, but is that true? How may of these UMPCs would exist if the Eee PC had never appeared. My guess is not many.
