I’m proved correct again.
Gmail isn’t only about a gig of space (anyone can do that)
But what makes it cool, and will continue to keep making things cooler is the innovation from individuals that use gmail as a base for new ideas/applications.
Take the GmailFS for example.
Mounting your gmail account as a file system is extremely interesting, esp for all college students who do not have access to a stupid USB port on the lab computers but do have access to *nix command-line and python compilers, etc.
There you go, a 1 gig flash disk.
Also, check out that Google Carto-grapher – not strictly a Gmail toy, but nice none-the-less.
