I haven't found much documentation for Thunderbird and what little I've found seems to say that all its good for is making my e-mail a little prettier. It seems to have no man or info pages nor a wiki that I've found. Does it do anything my browzer can't do without it or is it dead weight?
Does my Pidgin need it?
Does Ubittorrent use it?
Firefox says it doesn't need it.
My take is its specialized for e-mail for people who need be in touch at all times allowing them to not have the browzer open constantly. I'm no such person.
If there's any reason for me not to uninstall, please let me know. Its asking for a 30+mb. update.
