Well, I have no idea how Limpus Linux works (in fact, I hadn't heard of it until you talked about it).

Anyway, I can assure you Fedora, Opensuse or Ubuntu are pretty straightforward: click,click,click and you are done with everything :)

Why don't you just install a different linux like Fedora, Ubuntu, OpenSuse...

Well, that's the "beauty" of the closed source software if they use "tied up" approach. Eventually people will realize that's not acceptable... I'm losing myself here, you get my point though ;)

Evolution or thunderbird might work for you

dd if=/path/to/iso of=/path/to/sdcard

(if the iso is compatible with raspaberry-pi that is)

that was quick :)

Glad you could get your problem solved!
