I would hope a lot (the foundation have said many times, the RPi is not the only solution), but I don"t think that will take the shine off the Raspberry Pi for most anyway.
Personally I got a TI LaunchPad which is a little electronics dev board ($5), that has been great for getting back into the basics of electronics and wiring things to GPIO pins.
Also allowed me to start making some development modules for experimenting with (led banks and switchs etc).
Even when I get my RPi it will be useful since I can probably use it to feed analogue data in it"s ADCs and pass it to the RPi. Plus, I can test circuits without risking the "precious one".
On the software side, I've tried a few things, but the best solution I've found so far is from TeamPython, a live iso of RacyPy2: While you wait for your Raspberry Pi, why not use RacyPy2?
This has a few advantages:
1. It is a live ISO, so it will boot directly from CD with everything ready to go.
2. It keeps all your session data on your hard-drive or a usb key.
3. The very handy bit for me…I can run it as a VM (using VMware or similar) and boot to it in a window or I can boot using the CD and use fully, but either way the same user data is picked up from my usb key. If I want to use a different machine, I just use the CD or iso file and plug in my usb key!
I did use a few other options but I found myself re-configuring and installing etc over and over and not really getting down to doing any fun stuff. The above is up and running in a few mins.
