that makes a lot of sense, with that they have the option of having two-tier service.
the standard (limited) wispernet for free
unrestricted access for a fee
I know that for a reasonable fee (something less thhan I pay for an unlimited sprint card for my much faster laptop), I would be willing to pay for such a service, I would start off by loading a mail client on it (alpine in my case) for easy, remote access to my imap folders.
