I went with the Netbook solution for the last 18 months or so. It's small and light. The only problem is that it is a lot lot more fiddly in practice in a crowded bourse to whip it out and look up a coin. For a start one has to leave it on hot standby all the time (unless you expect dealers to hangabout for 5 minutes whilst you boot up so you better go with your battery charged). Then there is rarely somewhere decent to site and the only place to put it will be on the
glass tray tray. Finally, being miniature machines, the mice leave something to be desired, accurate cursor movement, clicking and, worst of all scrolling, are not the easiest thing to do in an atmosphere more like a crowded metro than an office.
That said, it fulfilled its purpose and was a lot better than not having it. This year however I went to a much better solution, I made my coin
collection up into a proper book, as illustrated here:

The Netbook is
still a great idea but a Book is better.
Regarding Doug's comment about databases: Netbooks are ordinary computers, just smaller, with less hardware add-ons and a little slower. They come with exactly the same programmes that you have on your desktop computer, although many users choose to use less-intensive programmes due to their lower power. For example Openoffice rather than clunky MSOffice. But they are basically exactly the same. So whatever suited you to store your coins on your regular computer should
work just
fine.
