'cept Sunray is no more:

"In July 2013, reports circulated that Oracle was ending the development of Sun Ray, and related products.[4] Scott McNealy (long-time CEO of Sun) tweeted about this.[5] An official announcement was made August 1, 2013, with a last order in February 2014.[2]"

Sunray as a service!

I used sunray's at university around 2001-2004. I actually remember them quite fondly.
