Out of curiosity, what parts of "communication device" are you missing on N900? Maybe we have different "communication" needs, but for me, it have everything that a communication device may require. VoIP, GSM, WiFi, bluetooth, MMS, USB Networking... Addressbook/calendar that allow soring more things than I'll ever, even remotely need. Tools for calculations, from basic, to highly scientific. Full office and image manipulation via LibreOffice and GIMP. I could go on and on (and wander even more far away from "communication" as per se).

But, again, for me 152374504354357 social media services are not a way of normal "communication" (although, from the threads that I see on TMO, people that like so-called social portals are using them happily, too). Still, I might be missing some super-cool-trendy-fresh-funky new wazzup-release-xxx7374-glamour, that doesn't have N900 client. Or, something like that.
