(I even co-wrote a book called The VDI Delusion, in which we essentially spent 240 pages explaining why VDI is not that great.) But VDI adoption has changed this year with the advent of two new technologies. The first is around storage. I always argued that virtual desktop infrastructure (VDI) had to be about persistent "1-to-1" disk images, but that doing so with traditional server storage was prohibitively expensive. This is why most VDI deployments have focused on non-persistent "shared" images, and why VDI adoption has remained marginal.
