  You can host your code on their servers.  Additionally, you get
access the memcache, data access, etc, deployed in Google data
centers.  The free portion basically allows you to provide 1 Gig per
day to users of your application.

  Well, beside's saying Google a beelion times, not too much.
Increasing resource caps is ludicrously cheap, so if a > 1 mil hits a
month site takes off, they have to pay.  However, the quota scale is
this (all units are per day):

  CPU Time:  Free Quota : 6.5 processor hours Additional Time: $0.10 per hour
  Outgoing
  Bandwidth:  Free Quota: 1GB Additional Space: $0.12 per GB
  Incoming
  Bandwidth:  Free Quota: 1GB Additional Space: $0.12 per GB
  Stored
  Data:          Free Quote:  1GB Additional Space: $0.005 per GB

  There are also other quotas on variouse services (only a *mere*
2,000 a day can you send, oh my), but they also have small microfees
associated if you wish to increase the cap.

  The only real non-dynamic per day cost would be Stored Data, which
would generally not shrink.  But then again, Spending a whopping $5.00
a month would end up giving you like 10 GB of data stored.

  I suppose it does make it much easier when a site grows to keep it
in the 'google family', as I'd have to increase my outgoing bandwidth
to be able to export my data in a day.  Bummer, dude..  :-D
