"the one that controls your search queries, e-mails, instant messages, photos, documents and soon phone calls without ever discussing an open standard that will let you manipulate all that data or let you move it to a new service provider"
Search Queries: OK, no open standard, but the interface is well documented - http://code.google.com/enterprise/documentation/xml_reference.html
Emails: Mail accessible and downloadable via POP3 - http://mail.google.com/support/bin/answer.py?answer=10350&query=Export+Mail&topic=&type=f
Contacts: Contacts can be exported to CSV (including a layout suitable for importing into outlook) - http://mail.google.com/support/bin/answer.py?answer=24911&topic=1530
Instant Messaging: Talk uses the Jabber/XMPP protocol, which is based on open standards - http://www.google.com/talk/otherclients.html
Photos: Not exactly sure what you are getting at here, Picasa is a desktop app as far as I know, so the files are saved locally.
Documents: Again, not exactly sure what you are getting at here, but Google Docs and Spreadsheats allows you to "save your files to your own computer in DOC, XLS, CSV, ODS, ODT, PDF, RTF and HTML formats" - http://www.google.com/google-d-s/intl/en-GB/tour3.html
Beyond that - Videos can be downloaded from Google Video, even if it iss just in a format suitable for use on iPods and PSPs.
They also provide a fair amount of information about there APIs - http://code.google.com/
How is that not allowing you to manipulate your data or move to a new service provider? Would you prefer them to talk about open standards more rather than actually using them where possible?
