While I'm promoting code...
If you're interested in never losing your keys (by generating them yourself), and are willing to learn some slightly complicated cryptocurrency (and bip32 specific) underpinnings, check out my do-it-yourself BIP32 tutorial here:

$ # from a live-cd environent (best), do:
$ apt-get install git python-setuptools
$ git clone https://github.com/moocowmoo/pycoin.git
$ cd pycoin ; sudo python setup.py install
$ # (insert the extra space at the beginning of next command, if not a live-cd)
$ export SEEDPASSWORD="auniquesentencethatdoesntexistinanybooksongorfilminanylanguageandhasatleastonehundredcharacterstobesafe"
$ # (very important: no spaces, no punctuation, no capitals == nothing to forget!)
$ # (double check your passphrase!)
$ echo $SEEDPASSWORD
auniquesentencethatdoesntexistinanybooksongorfilminanylanguageandhasatleastonehundredcharacterstobesafe
$ # (triple check your passphrase!)
$ echo $SEEDPASSWORD
