Google Acquires 15 Companies in 2005

Google disclosed in today's 10-K filing that they acquired 15 companies in 2005. They "acquired all of the voting interests of nine companies and substantially all of the assets of six other companies."

I can only come up with a few of these companies:

1. Urchin Software - now Google Analytics
2. Dodgeball
3. Akwan Information Technologies
4. Reqwireless
5. Android.com

Anyone know the rest?
