Don't be an idiot like I am: Resist the urge to have the "latest and greatest" OS X

People should start using Time Machine. Seriously, I love Time Machine.
If that kind of thing happens, you can restore the entire OS from a TM backup straight from the recovery screen (disk if you have one, built-in if you don't).
Thanks to local snapshots, it even works offline now for recent changes and uploads those revisions to your TM when you're back. The biggest issue for the very paranoid was data reliability; but now since you can do alternate backups to different disks even that should be solid.
Apparently it's even supported with USB drives attached to the new (tall) Airport Extremes, but if you have an old model there are plenty of guides available.

I don't have a problem with always installing the latest and greatest...when it's stable 
. Then again when I ran Ubuntu I used to install development versions all the time and used them on my main machine, it was probably stupid but I didn't care since I tend to take the risk first and then deal with the consequences after. When I got a Mac I certainly was less confident to take such gambles though.

Update: Computer back up and running
Hi all:
My i7 iMac is back up and running. I did a fresh install of 10.9 after copying the contents of the bootable SSD over to the OE 1.0TB hard drive and wiping the SSD clean.
The new install is working well. I've noted a few broken pieces of software--ClamXAv being one of them (Error #134, whatever that is)--but nothing overly glaring at this point. I can't comment on overall system resource use (compared to OS X 10.8.x) as iStat 4.x that ran under 10.8.x appears to be incompatible with 10.9.
I do appreciate the many of you who attempted to help despite my mistake.
Regards,
Rob

I'm a med student who only uses safari and mail and calendar really. Maybe word and iphoto here and there. Photoshop if I'm feeling fancy. I made the leap. I guess that's considered little enough?

I installed istat menu on 10.9 and it runs fine. Preferences window sometimes crashes but that's it.
Something is borked in your mac, maybe try a reinstall.
I'm running 10.9 here on my 2011 MBP 15" and have had zero issues other than a few system preference panes missing graphics and just having blacked out bits.
Mail works, terminal works, etc.
Not saying you have no issues - just saying that maybe you can fix it and still run 10.9. Works pretty much fine here and I"m preferring it to Mountain Lion purely for multi monitor full-screen and the power consumption.
You did take a backup prior to installing, yes? Worst case scenario, I go back to 10.8 and restore from backup... no big deal.
Home machine. If you're installing it for work you're nuts, unless you're a paid developer and it is your job to evaluate

Reiterating what everyone's already confirmed, I'm running OS X 10.9 DP1 as smoothly as 10.8.2 ran; if not I dare say better.
Scrolling is like a knife through butter, HandBreak is so fast I can't make a cocktail quick enough to put down when it's finished and developing seems easier with some new SDK's and the latest Xcode.
I'm using it on my production rMBP 15" (2012) - taking precautions such as data backup, Time Machine backup and also a HDD clone just incase.
If you want to get DP1 because you're like me and you want to get into anything new ASAP, then take precautions - and stick to genuine developer accounts!!
Happy dev'ing

Frankly, it's been lost on me, too .
If full backups/clones are not part of your daily routine, and are not done even before moving to a new DP OS, then the entire point of the thread is : back up and clone, repeat at least once.
Add Time Machine if you want to, just don't rely on it for recovering changed OSs , nor on recovery partitions.

if I were you I'd also test those backups from time to time as well to make sure you aren't backing up garbage. I think Carbon Copy Cloner also does some checks when it's backing up as well....
AFAIK, many developers choose to run an image backup of their system prior to installing a beta OS, that way they can easily downgrade. I suspect the recovery partition that is now created in OSX only complicates things.
I feel your pain OP, and I'll not say anything other then the beta program is designed to shake out bugs and give developers time to review the changes in the OS to do their fit gap analysis and update their apps.

The medical definition for this behavior is!?

Not if you select the entire device (HDD/SSD) in Disk Utility. In that case, DU or Apples asr copies & and compresses (if you selected this option) blocks from device and stores them, including a checksum, in a .dmg file. In that case your .dmg file contains the contents of the entire SSD/HDD, including the recovery partition. You just need one large external HDD/SSD for the second bootable OS and the space for the big .dmg-file.

Are you from the future?
There's no such model that I know of. I'm guessing you either made a mistake or you think just because you bought it during the year 2013 that made it a 2013 iMac.
Despite my previous replies....
I went back to Mountain Lion this morning. I used a backup made by SuperDuper to restore my iMac.
The decision to move back to ML had nothing to do with the stability of Mavericks.
There was one single program that would not work under the Developer Preview....
Elgato EyeTV.
Since I spend hours on my desktop I depend on having a television feed in a small window on my second monitor. Under Mavericks, the EyeTV software constantly crashed.
One more thing...
Aside from performance enhancements, I saw very little visual improvements over Mountain Lion. In other words, it seemed like business as usual and thus, there was no rush to upgrade to Mavericks.
I will still emphasize that DP1 is extremely stable and that your choice to upgrade should be dependent upon what programs actually work under it at this point.

I had several issues with 10.9 after doing an upgrade from 10.8... I thought that they were issues with 10.9 and I was ready to go back to mountain lion almost immediately.
However, I was stubborn and still wanted to try 10.9 so I created a usb install for 10.9 and did a clean install.
Most of the issues I noticed have gone away with the clean install.
It is definitely not "production ready", though.. which is to be expected due to the fact that it is an early build still in development.
Loving the improvements, though.

I had more issues with a clean install than an upgrade from Snow Leopard... no kidding...
You clearly don't use your Mac for a lot, though if you would want to write a paper or a thesis, you shouldn't install any beta software. It's strange how even many people who are interested in IT don't really use a lot of the functionality their machine offers; most stuff happens online, so it doesn't matter as much which computer you use. If you don't play games very often, most computers of today are actually a bit overpowered.
I have used 10.9 recovery partition to restore Mountain Lion backup and had no problems.
