Error -19 upgrading to 1.1.4 (including resolution)

Question

Upgrading an iPod Touch is always an adventure. My first attempt resulted in an unknown -19 error code. Repeated attempts to install resulted in the same error.
I resolved the problem by a complete restart of my PC, then unplugging all USB devices, then plugging the iPT into a USB port directly from the motherboard (at the rear of the PC). Once iTunes fired up I tried the 1.1.4 install again with -- breathing a sigh of relief -- successful results.
With the imminent release of the SDK I hope future iPT apps will not require all fingers and toes crossed in order to install them!

I just had a very frightening experience upgrading my touch to 1.1.4. After the update it told me my ipod was damaged and it needed to be restored. I use my PC to update the ipod. After 4 or so tries it was doing the same thing and I was getting nowhere.
I had to plug it in to my mac in order to resurrect it. It also only worked on the second try on the mac. Mac's seem to have a strange ability to resurrect dead iPods that PC's don't - this also happened on my nano.
After that the January software update was gone. I tried to sync with the PC again, and it went back in to the restore screen again.
Back to the Mac, restore again, then back to the PC and it synced. But still no January software update. Eventually it recognized my ipod and restored it from a backup. This took about 4 hours of my time.
Apple, you are letting your quality slip.
