While that sounds good in theory, having one language to devolpe for focuses developers on solving problems, not spouting acronyms. It also makes suppirt a lot easier; and forces the hand of innovation to those developers who don't like being told that developing an app in another language is impossible.
The term 'devkit' is problematic anyway. The OP has listed languages, application and UI frameworks and whatnot in a single category, that's pretty much apples and oranges there. Especially as Maemo is a full-fledged linux, so listing languages and frameworks is a bit of a hmm.

I could have guessed the results of the poll from the start, really. I think this forum is a bit biased... 
Perhaps the poll should be about which device will be the greatest threat to the N900's impending popularity. That would be a bit more interesting.

Just some corrections for the front article.
22. Dev Kits ---- C QT Java WebKit Flash -- C Native ------- WebKit ------- C QT Java WebKit Flash
OS X uses Objective C which is far from C, more like better C++
26. VoIP/Skype ---------------- Y ---------------- N ------------------ N? -------------------- Y
http://www.skype.com/download/skype/iphone/
About Objective C - is this the same as OpnStep C or NextStep C?
If yes, this is an advanced OOP but it is different than C++.
So iPhone cannot run C++ programs or Java programs.

Dunno about those languages, but I didn't say Objective C is C++, I just said it is not C.

Objective C is a superset of C++ and thus is generally a superset of C. You can add .cpp files directly to your Xcode projects, and I'm guessing the same goes for .c files.
What version it's a superset of is left to the reader.

If you call 'jailbreaking' equal to 'power user' then I think 'normal users' aren't able to do much on any device, including using Maemo's Application Manager. Jailbreaking is easy as pie, and the instructions are quite clear.
Legal matter, sure, that might be a valid argument. But most users don't care for that and frankly, I believe I am fully in my right according to law here to jailbreak.
I don't know about C++ applications, but if you have a look in Cydia there are tons of useful applications available on these repositories. To install them is about as easy as using Synaptic or Application Manager.

Historically the C++ ABI has been a mess and it was very difficult to link C++ code with anything. Things are better now, and there's even an "Objective C++" but don't try mixing C++ and Objective C classes, namespaces etc unless you like living in interesting times. Mixing either language with C is much more straightforward of course.
I hope not 'cause I just became comfortable with Objective-C memory management.EDIT:
Yes, not to contradict myself too much further, you are right, C++ is not a subset of Objective-C.
