I guess the OP already got its answer, but nevertheless. I'm right now sharing my 3G connection in my N900 over wlan (using mobilehotspot) to my laptop, to jump my ubuntu installation over two versions to Meerkat. The only reason I'm doing it this way is to piss the living hell out of my operator Sonera (whom I fervently hate). Recently, Ive found I don't really have enough time to tinker with my N900, and that makes me really sad. It would be nice to test properly new apps, write bug reports & suggestions for improvement. Alas, I'm sliding more and more towards just discarding an app that doesn't work perfectly for me. As for maemo being obsolete, I'd disagree. After one year, it's starting to feel mature now. It's almost like having had the phone for a year without being able to fully use it. The N9, or whatever the meego flagship will be named, will no doubt have its own issues, and it might well take yet another year before this community has made it into a usable platform. So in that respect, I'd recommend you ignore the people telling you to wait, and just buy the N900. I just checked the official specs, and for some weird reason, it really seems to read mc limit is 16GB. Which is really funny, because nokia makes it's own brand of memory cards, and I'm pretty sure the MU-45 32GB was out before the N900. Also, the official Nokia accessory lists had listed a lot of phones as 32GB-compatible already a year before (sorry, no source, I just know). In any case, as some have already said, you should be able to use any mc of any capacity made available later. I also applaud for your efforts to do research in advance. It seems a lot of people here (the whiners) didn't do that. In any case, be prepared, that a of of things won't work out-of-the-box. Finding a satisfactory solution might take hours of googling, tweaking and swearing. In the end, it might still not work, at least not the way you'd want. On the other hand, with other platforms, you'd never have the chance to try - either it's there or it's not. To conclude, if you are the patient sort of guy (which I am not, but my apparent masochism seems to work out, too), this is a phone for you. Otherwise, don't bother.
