htc hd2 and some samsung galaxy phones are the only ones to my knowledge (limited as it is) that run 64 bit ...currently....
as aged as the htc hd2 is...
it's still a beast.
what did it run again?...
win 7 8
ubuntu
meego (if it could run meego then this device is def. something to look at..who knows ...perhaps nemo then may work...doubtful sailfish...perhaps freemantle will work when it is done...hhmmm...if meego ran on it...then mer?...possibly?...)
and as far as droid goes...I heard months and months ago that someone got lollipop to run on the hd2...
beasty is unkillable...it keeps coming back from the bloody grave...
and even though it is as old as the n900...
the hd2 is STILL a wanted and coveted device...

Sorry for late answering. There is X on Android:

and you can also use vnc if you like to.

Is there a package for Maemo ui for Ubuntu or Debian? I could try it on my setup on my Android device.

I doubt it would be for maemo5
It would likely be for maemo4
hildon to gnome was the last I heard of work being done on it...
https://wiki.gnome.org/Attic/Hildon/Building
UME is another alternative...

Moblin is prolly more current than the preceeding
I think meego is prolly the last to recently run on "other" handheld devices than maemo...
there is this for buntu...
https://blueprints.launchpad.net/ubu...top-for-ubuntu
a little old...(2007-ish)
there is this for debian!
aha! little more current...squeezy...
https://packages.debian.org/squeeze/hildon-desktop
yet again I think it is more of an earlier maemo desktop than maemo5 though...

Maemo5.. even Maemo4... would be fine...but earlier?...
naw...too rough..for the desired outcome.

Best bet is...
you could pilfer moises maemo5 work for what is needed...

There is of course another option I just thought of...
rip the ui out of the latest linpus lite...
That definitely comes closest to our ui....
very touch friendly...
has the maem-esque look and feel...
based off a very very modified version of cinnamon (i think) and moblin 2 originally...
meant for big or small screen...
Linpus lite is a sparse os with not alot of software (compared to some os's)...
but the build structure of it's ui...it's desktop environment is...(what's good words here)...familiar and cozy...yeah...
that alone makes it into my "odd-ball" favourite distro pile short list..
I like to use now and again...

I have a small folder of pertinent urls and files on this topic..
I do not believe age being a factor since the wealth of experience from each of the attempted or successful methods has value...
Never know when something old ends up having validity in the present....

As far as course of direction to take considering the desired outcome....welllll....that is the question ...
As far as windows phone, iphone, even android...I am COMPLETELY ignorant of the respective operating systems ...never having desired to have (in the past) one....I never bothered to learn...as far as distros for handheld...it has been maemo based for me from day one...
so I am quite clueless pertaining to what could, would or should run on any of those devices...
Now...
get maemo running on android ...properly....
and I will rethink my philo.
pick up a competitive device and continue on quite merrily...
Come to think of it...
if maemo ends up running on droid....
think of the number of android converts we could get ....

what about Surface Pro and OS of your choice. Might be a bit big but plenty powerful.

My problem is that I can't see myself using the Surface Pro as anything other than a laptop. I can just imagine walking down an aisle of a grocery store and whipping out my Surface Pro to run a quick Google search. The thing is just too big to carry around while you're doing something else. You kind of need to be sitting down to use it comfortably, and in that case, there's no reason not to attach a keyboard to it...

yes yes yes
i sold my tablet for the same reason only thing it did properly is brousing in the bus but then it caught too much attention

actualy daily like two people will ask about my n900 as whats that and then woo and wah people confuse it toca camera some say its like a computer i was done sold my tablet and have to face less people most curious ones even open the terminal and type random sith to see if is linux one even tried rm/rf god saved me as he typed it incorrectly and said ha ha its a fake i saw the screen and my heart stopped like disc brakes i said its a chineese clone and speeded out of his sight as fast as i could and that happend today

so one big question how to block critical stuff in n900 that can do serious damage ?

A big 3 foot sign attached to your n900 saying...
"If this isn't your personal property....Keep your bloody mitts off"
...
or...
more discreetly....
walk around with a car battery and jumper cables in your carry-on bag and hook them up to your device while not in use...
personally electrified anti-theft...

I let people touch my dog,
my cat,
hell...my "junk" ...
EVER before they touch one of my nxx0's...

I don't care if I hurt their feelings when they say "lemme see that for a sec. .." and I say piss off...
I don't care if they are dying in front of me...
Nobody get's their greasies on my nxx0 for any reason...
I don't ask to see someones personal info, their credit cards, their bank statements, their personal and business contacts, their work,...the list goes on...
asking to play with my daily or work machines is very personal...and very dangerous...in many ways...
so nope...
not happening...

friends want to see cool stuff... I ..myself...personally show them..without letting go of the device for an instant...
or I give them a back-up beater to play with...
Never my own nxx0's...

But back to the issue...
maem-esque ui on android...

Personally I think the way to go that has fewest hassles trying to get it to function is...
I'd dissect linpus lite.
best suggestion...
it is as current a running ...functioning... example as it gets...

No.

Maemeque interface on Android is NOT the way to go. I don't want a crippled OS.

The way to go is to run a real Linux distro (e.g. Debian/Gentoo) on some device. Need Haskell? Apt-get it. Need OCaml? Need Brain****? Need a fully fledged source code editor or a modern CAS? It's there for you to install (Debian) or compile from source (Gentoo)

I agree with you completely on debian running on handheld...
I just like the desktop environment .....the surface ..the skin of maemo...or something similar....meego-ish..nemo-ish..in look...on top of debian...is all.
the underlying guts I'd prefer to be debian...over gentoo...or any other distro...frankly...
