Friends don't let friends rely on free web services.
* Code Search -- how did I forget this awesome tool? What an invaluable, educational, and fun tool that was.
* Google Video -- somewhat redundant with YouTube, but I always felt Video had a place in that it seemed to be much more liberal than YT and also allowed larger uploads.
* Google Desktop -- ok, this one did hurt. My primary use for it was to search my Outlook mail at work (f'g Outlook search is the worst I've ever seen in any product). Now I'm back to never being able to find an email...
* Google Notebook -- a very awesome online clipbook / personal wiki. I still miss it.
* GOOG-411 -- I still miss this service too. Going online is just too slow and tedious, not to mention impossible and/or illegal when you're driving (whereas hitting a speeddial for GOOG-411 was quick and easy). And no, the "voice search" on my phone is not the same, not even close.
* Google Health -- this was a very neat service that I think was ahead of its time, and I didn't use it much (as I didn't have many health issues at the time), but as I age, I'm wishing more & more I had a centralized location to store my medical history on my terms.
* Google Dictionary -- another tool I used on a daily basis. At least there's an official extension that I can use in its place that is functionally equivalent (for my uses); just turn off the pop-ups and invoke it manually from the button.
Pretty scary how many of my tools and services that I came to rely on were shuttered; however, I think the powering down of Reader will impact me the most.
