I made a dedicated in-wall shelf for my Chumby One. I use my Chumby next to my bed for listening to news in the morning, for weather, internet radio in the evening, and to stream my security cameras. I also use the usb port to charge my phone.

Mine's sitting on my sort-of desk-nightstand-table atop the gigabit switch that runs my bedroom

I often take it down to toy with it - consequently, the FM antenna hugely gets in the way when I go to set it back down, I think I'm going to either put that back in the battery area or tape it down. The headphone/audio-out jack is really loose and the plug falls out a lot when I move it around, which is a minor annoyance since the cable isn't long enough to move it far anyway (I often unplug it when I'm playing with it).

I can't think of a reason to have a Chumby anywhere except my bedroom as an "alarm clock+". It's a good fit and I'm not quite regretting getting rid of my real alarm clock, except for when I go to look up at it for the time and it doesn't have a clock on the screen. I really wish it had an option to always force a clock in, say, the upper-right corner. My PC always has a clock in the lower corner and I'm finding myself looking there all too often now

My first Chumby is in the living room, next to the TV and connected to the stereo to play internet radio. Most of the time it runs a channel that has various clocks, including my all-time favourite widget 'Sky Happenings', the weather, Picasa photos and a few novelty widgets that look OK from a distance, like the Lava Lamp. If I've got something on the stove, I'll change it over to the Toasty Timer channel.
My new Chumby One is in the bedroom. I haven't completely sorted it out yet, but it plays a night time channel of darker widgets, like develephant's Moods: Snowflake and Moods: Star Warp and a morning channel of Google Calendar, Gmail, weather and a few news sites, liberally interspersed with the time.

Next to my bed on the nightstand. My Chumby (his name is Sammy BTW) replaced a traditional alarm clock radio. I wanted a internet music streaming radio for awhile (got a Slacker G2 already) with alarm functions but none of them impressed me as much as the Chumby since it can do so much for so little cost.

I already want another one for the bathroom. Don't laugh, I spend a good 15 minutes in there every morning shaving, brushing teeth, getting dressed, etc... and having the news, weather, stocks, email scrolling by would be perfect. Mounted at eye level next to the mirror would be perfect.

At my bed side.

I listen to audio books (USB) at night on the timer.  I get woken up by the World Service, with back up alarm.  It then plays my info widget (weather, email, news, clock).  Then I either turn it into a picture frame (using the picasa and flickr widgets), or my large channel (full of all the other widgets I enjoy).

Saturdays I get woken up to the BBC R4 friday night comedy podcast, and Sunday, the BBC R4 Saturday live podcast.

OK my original Chumby is in my office and my Chumby One is on my night stand. I used to move the Chumby around a bit but I also got a squeezebox for my stereo in the lounge room so all devices now stay put.

My Classic sits in my living room. I mostly use it to keep an eye on email while watching the TV and to read newspaper articles and check the weather in the morning so it hardly ever moves from there, unless I want music while cooking. Another great side effect is that it has pushed my office back into my office.  No more roaming laptops!

Near my side of the bed, on the nightstand, with backup battery too.
It is used as an alarm clock, look at the weather, etc.
It does not replace our "real old-fashioned" alarm clock so we have both: Chumby, sit at my nightstand and the "real alarm clock" at my wife's.
Since it has a battery backup, I sometimes take it with me along the house but it stays 99 percent of the time in the nightstand.
BTW, my wife doesn't like the Chumby: says it is ugly and useless but I disagree with her.  :-)))

My cumby is in my bedroom.I use it as an alarm...

My new chumby one is also in the bedroom as a clock radio. Kids love it though...

We have 3 chumby's, one is a Chumby 1, the other two are the Insignia ones from BestBuy.  The Chumby 1 is in our family room on the side table and gets used the most. The other two are in the kids bedroom and are used as alarms clocks and playing their music before going to bed.

I wish I could use the chumby at work but there are two thing,  corporate WIFI certificates are not supported and the darn proxies!

In the living room acting as a web radio/digital picture frame.
