Kent, I have had notebooks for round about 6-8 years with the oldest I have being an Apple PowerBook G3; got that when I went to university some 6 years ago or so and it was second hand then....
When talking about production though, the notebook is really slow now as it's only a 400MHz PPC G3 processor so the system is only used as a console interface to my SPARC servers sitting in my lab at home, please see the link from an earlier post. My point is that although desktop and laptop systems may last for ages they slow down after a while once software starts becoming more advanced. Because of the design of the DTU's all one needs to do is change the server within the interconnect and you have literally a modern hyper fast system again, this scales exceptionally well for large networks with large either dedicated or multi-access interconnects. Fine so the res might be a little low and the slew rate on the headphone amps may not be as fast as a modern day Ray audio chip which will have a better SnR too but so what.... Thinking about it, a server will set one back say... £2000 x 2 for a failover that's £4000 ok that should be enough to power at least 30 DTU's!!! Try that buying a desktop for 3 x as much as a DTU plus a server for authentication and storage one will end up with approx £10-£15k expenditure plus any extras for server and networking equipment. For standard office work they are brilliant and even for homes as I put in another post a few days back...... I really wana see them in web cafes but that's a bit difficult considering the average person does not know about Solaris let alone UNIX unless you set it up to rdesktop into a Win server at login, and I also wish that Surrey university (just as you mentioned that you were from Sun UK) used them back when I did my degree in electronic engineering. Actually I wish the place where I'm doing my Cisco CCNA at Grafton College used them too but my friend who is the college admin is scared of touching anything UNIX :-( Oh well...... Do you need a good sales person btw???? As long as I get to do engineering too I'd be really great :-) ...just kidding you guys are cutting costs and the last thing you need is some newbee with binary flowing through his veins lol Kaya -----Original Message----- From: Kent Peacock <[email protected]> To: Rob Giltrap <[email protected]> Cc: SunRay-Users mailing list <[email protected]> Sent: Wed, Jul 22, 2009 2:50 am Subject: Re: [SunRay-Users] How long have Sun Rays been around?

Would be nice to have some real proof of their > longevity (both in terms of the units and the architecture). It would seem my little survey constitutes that proof.
