Yes, we do b1tch m0an and compla1n regularly, but -

Just to underline what a lot of good folk have said in the posts above:

If all you want is a phone then you probably want to look elsewhere.
the Androids, WinCrap and iCrap all have some lovely features
which you may never see on the n900 (compass?)
But all those devices have shortcomings which even their fanboys
eventually acknowledge (camera quality, memory limits, trojans, etc)
These are in addition to the limitations of the OS they use.
They excel at being useful out of the box for merely what they
were designed for - a phone with some mediocre ability
to have a few minor applications added.
None of them run OpenOffice, or are able to hack a network,
or have the entire Debian application repositories to work with.
You cannot really see inside them, they have features hidden or
otherwise locked down by either Google or the carriers,
and the applications you install on them may have some
'interesting habits' which may require packet inspection to discover.
But they are quite competent at being simple phones you can slap
a sim card into and be on your way without any particular grief.
And in that regard they are a better choice for 'Joe Six-Pack'

If, however, you appreciate the ability to modify what you purchase,
then the n900 is in a league of its own and without peer.
Just do not expect any support from Nokia - that does not exist.
And remember it is a one-of-a-kind device and there is nothing
coming later to upgrade to.
The n900 is a beautiful b@st@rdized orphan
abandoned at birth by the very people who created it
but which with a little bit of care can be made to do just about anything.
(Except Flash, of course)
