I guess you didn't read/understand.
The eeePC 701 is an exceptionally small machine: KB, HD, display.
Most O/Ses will fill up display or HD. Puppy fits in HD but some text dialog boxes are hard-coded taller than the screen. (Oddly Win XP runs OK in a 480px tall display.)
I have been hated by unix since the late 1970s. Layers of puffy candy do not make it better.
Not updating Samba sounds like a very serious risk. File-share virus/worms are still around. Windows networking is horrid to begin with. "Security" is all tack-on, and often it is just easier to go through a gap in the side. Not well documented in detail (and much of MS's docs are just wrong). Samba tries to track MSnet but it is a never-ending problem.
I didn't notice the eeePC part right away.

We did run versions of Linux on the few netbooks we had. With reasonable success.
Now most smartphones are more powerful than the netbooks we have.
And they are Andriod OS (Linux derived).
Samba may not have been the best example of a service to pick, as it's not needed unless you share resources on a Windows network.
Almost all file-sharing virus/worms are Windows based, so even if you catch one they can't eat your Linux system.
While in Korea, Ubuntu Linux was the only OS I would install for my wife and youngest son to use on their PC.
They would get any flavor of Windows virused up in less than a month. Ubuntu ran for over 2 years with no problem.
They never ran any updates, as users they couldn't, and we never had any issues.
Most people do that Linux eeewww thing. They never really tried it enough to find out about it.
They would rather give MSFT $100 of their hard earned money to get buggy software that locks up/crashes alot.
Then they need to give MSFT more money for Office, just so they can do things Linux users get for free.
IMO, If our politicians didn't need to be bribed with that MS licensing $, we would be using free/more secure Linux OS's on our Govt computers.
