This is not the status monitor you are looking for...
I posted the Droid's battery usage monitor as it kinda confirmed what was "its" battery hog (screen/brightness). Problem with the 900 is that even when its "idle" (i.e. I can actually get myself to put it down and walk away) it still won't last 24hours.

So basically.. if Android had Conky and I was running your conky script it would show me as running 58 processes (and that's still probably not the full picture, since androids "ps" doesn't have any options like "ef" or "lax") - but I only see maybe 10 at any given time in the various process monitors that android has.

Android isn't real (read: GNU) Linux 
. Android has JUST the linux kernel, and then the dalvik VM overlay. So what you're looking at is there are 58 processes.. take away maybe the 24 that I can control with the advanced task manager (since I'm thinking it only sees the processes within the dalvik) - leaves a little over 30 *just* for the core OS/Kernel+raw Android.
In Maemo.. you have that 30, plus additional that the base Android would handle itself.. like Sound, X, Multimedia, etc. There are like 5 or 10 just "hildon" pieces that run just to give you the basic Maemo interface, for example.
I see your point that 186 seems high when looking at others... but just trust us - it's not that bad
. (Unless of course someone else gets on here with a perfectly functional N900 and claims they only have 58 processes running to.

Classic example of arbitrary Nokia decision making. Couldn't just fallback to the no brainer of tagging with lat/lon if network isn't accessible, could you Nokia?

I have had WiFi on all day, connected to my SIP account and Skype conncurrently, along with (3) email accounts, and OM Weather polling every hour. Even with WiFi on, and the phone "sleeping", I can't imagine much data being transfered for "keep alives". I still don't go 24hrs. even on 2G/2.5G, when also factoring in maybe an hour of general use.
For what its worth, it seems like drain rate has increased over the past 2 days, given same useage patterns.

My slimmed down Gentoo box running minimal applications except what I typically use. We're looking at 3 terms, audio, pidgin, a webbrowser, xchat, and two gkrellms and I'm looking at 253 processes. Though, the composite total of cpu used across all four cores is only 1-2% as I type this. (No individual processor is spiking over 9%)
I also have an eight core Fedora install for a client for samba sharing and just your normal network services for a business and they're looking at 522 processes. This install is bloated as hell (done by another admin) with literally nothing done to slim the base install and it's only running composite cpu at 25% max, for a network of six users.
So really, it's not at all in how many processes you're running. Most of mine on this box are doing nothing but sleeping, and even with 250 processes running I'm still only seeing very low cpu usage.
Normal processes go to sleep when there's nothing to do anymore, and they pretty much just idle there not doing or using very much.
I've had linux boxes running on Pentium Pro 200mhz machines with 96mb of ram running 128 processes (and more); It's all in what those processes are/are doing!

ps -ef | wc -l
reports 157 processes at the moment (three of them would be the xterm, the ps, the wc). That's just fine, and normal. The important thing is that 'top' shows 1-2% CPU and nothing is running wild. Battery time is good.

When you installed Conky there, would the number of threads you saw be significantly different?
why did this get moved to the OS forum?

If you go in to xterm as root, and run:
ps auxw | more
you can page through the list of running processes and see what's going on.. it's really quite educaitonal, especially if you google all the ones you don't immediately recognise
One thing to be aware of is that kernel threads will show up as processes, for example, from my ps output:
are mostly kernel threads (the square brackets indicate that, iirc).
Also, a lot of the hildon stuff seems to register twice:
probably because of the way the code is written - I'm guessing there's a parent process which has spawned a child process and is ready to spawn another one if the child dies, or something like that ..
On my N900 I seem to have fewer processes than you:
so only 140. I guess applets and desktop widgets might account for the difference?
The real factors, though, as mentioned, are cpu memory usage, the number of running processes is of mostly academic interest if those two stats are ok.
The cpumem widget can show you both of those.. Mine tend to be at ~130-150M memory use, and ~3-5% cpu use when I'm not doing anything on the N900, which seems fine (I have only a couple of desktop widgets installed, cpumem and slideshow, I also run sshd and camkeyd)

Duh. I have a rooted Android.. lets see here (pulls out of pocket): Advanced Task manager shows.. 24 processes, and 6 applications running. As root in a shell: ps | wc -l shows 58 processes. Yeah - it's not showing everything
Linux is a little different. Just as an example.. on a Linux apache server you can have 60 or more processes *just* for apache.. not including everything else (on a higher load server).
So basically.. if Android had Conky and I was running your conky script it would show me as running 58 processes (and that's still probably not the full picture, since androids "ps" doesn't have any options like "ef" or "lax") - but I only see maybe 10 at any given time in the various process monitors that android has.
If I've helped you or you use any of my packages feel free to help me out.
