And another in the wings as drizzle - a fork of mysql. This is getting a lot of attention and some parts are considerably cleaner and faster than mysql.
I agree with this, too. The sunrays are excellent.
But I think the OP is still missing something here. The transition to VDI is not just about replacing one box with another doing the same old same old. It is also an opportunity to start to transition away from local storage, login, screen savers, etc. While there are many many advantages at the back end, there are also some significant gains at the front-end, too.
As an example, the sun rays have card readers that allow you to authenticate to the back-end very quickly. Using this feature you can roll out always-on desktops that let your users sit down at a desk, any desk, pop their card in and get their desktop, just as they left it, anywhere. As they get up, their card goes with them. No need for screen savers and the whole thing is very very fast. This kind of facility is a big win for our users. No more logins! No more password resets!
So perhaps consider VDI as a way to seriously improve the end-user experience of computing.
Anything cut to length will be too short.
