I like & use AWS quite a lot (all those http://pfein.s3.amazonaws.com/ urls 
are on S3). It's fine for personal use, backup, maybe serving static content 
& large files (they have BitTorrent seeding support, IIRC).

Speed & esp. latency is an issue though.  And the AWS network bandwidth charge 
is expensive.
