i bought an n900 thinking in sony vaio ux 280p
an computer in a pocket size with touch screen.
and really i do enjoyed the experience with n900.
unhapilly i had to sell my phone some months ago.

i never touched in a android smartphone except for 5 minutes because the person that bought my n900 wanted it with dual boot.

i have 150USD to expend on a smartphone
when i bought my n900 i bought for 200-220USD,i think it was last year.
i knew i was buying outdated hardware but it fited my needs.

i asked in many forums but nobody used a n900 to know what i am talking about,how it is feel in our hands a hacker phone an all in one swiss knife eletronic

all they know is about facebook and whatsapp
but to me these things are superficial/basic and boring,i want control , i want explore my device until the last megahertz, the last byte.

my doubts and needs,
with android 4 ICS or superior will i be able to:
#use my ps3 controller and control my emulators like in n900?
#record internal sounds and voice calls like in n900?
#do bluetooth tethering,hotspot wifi and use as modem like in n900?
#inside easy debian it has a "movie maker" similar program to make simple video editing,in android will i have this program?
#mount .iso images open zip,rar and infinity of extensions and compile programs like in n900?

very nice functions but due to budget they become dispensable/luxury:
usb otg
tv out
camera with focus/hdr and iso adjustable

i was searching,i found these phones:

can i root them?
are the apps the same?
what do i need to know about android vs maemo?
i've heard that android consumes much resources because it is programed in java and maemo in c/c++
and with 512 of ram the phone with ICS is slow,with 256 ram is unusable
is that true?
someone played with ubuntu touch?
i want a phone customizable, so what is the best deal/choose for me?
