1. The Droid has a bigger screen, a higher resolution, a capacitive screen, multitouch in the EU-version, it has a stronger battery, t's got an internal compass, it's got a four row keyboard, and still manages to be thinner and lighter. It includes more software, free turn-by-turn navigation in the US, almost all built-in apps support portraitmode, full flash is upcoming. It's lacking an FM-radio (who needs it when you've got stream anything u like from the web) and a frontcam (although that isnt even properly supported atm in Maemo) - but if you really needed then you can get the Saygus V1 Android Phone which includes both. The Droid also has some very nice accessoires, like a Cardock (which loads up a Homescreen optimized for in-car usage automatically) and a regular dock (which transforms the device automagically in a photostand, nightstand clock etc).
2. The future for Android in 2010 is looking very promising. All this excitment about "the best browsing experience" wont be for long. The Droid (Milestone) has multitouch, bigger screen and higher resolution. So with upcoming Adobe Flash 10 support and the mobile Firefox (Fennec) the Droid will properly be a better Web device than the N900.
And all this porting of Linux apps to Maemo: wouldn't proper ports require some serious work in the UI-department? a smaller screen, lower resolution, and touchscreen; so a developer would need to rewrite bits of his UI (such as bigger buttons) for a mobile device. The lack of a portraitmode is a serious showstopper for consumers. Everybody is used to using the phone in portraitmode. The N900 is a smartphone afterall; not a tablet? Yeah, it's upcoming - but so is Android upcoming with full flash, fennec, and even more social integration.
Oh and if development is so easy for Maemo: where's the MMS-app, where's the portraitmodes, where's the Ovi Maps 3, where's the Google Apps?
5. How free is Maemo? There's actually not a lot to choose from at the moment. You've gotta pick Nokia's N900 if you want Maemo 5. And in the software department there's not a lot to choose from just yet either. So how is this freedom? If I want Android: I can pick from 20+ phones, several carriers, and several phoneset-makers. I can choose to run GoogleNav, Sygic, Destinator, Co-pilot or whatever.If I want a music player, I can choose from 50+ programs. And 100% OSS is not even the goal of Maemo (OpenMoko is btw), but more like 80/20. They do want to keep (just like Google) several propertiery Nokia software out of the Maemo OSS-cloud.
So even though I'm very excited about Maemo (the whole concept of it), I'm going to stick with Android for a little longer; and hope to see Maemo 6 very much improved near end 2010!
They're maemo and MeeGo... "Meamo!" sounds like what Zorro would say to catherine zeta jones... after she slaps him for looking at her dirtily...
