Wow, so all sales people are bad right?
Yes I work in sales, though I trained in IT/Networking and that is where I started, and while in Sales I am of the technical sales, so giving demos and the like.
Hate sales all you want, but without sales people then nothing would progress and most people would not have jobs, also the best sales people actually tell the truth, especially in a SaaS/Cloud model since if you sell on a lie people can cancel right away so it would only bite you in the arse.
Now does physical kit have a place and have pros? Yes. Does that mean Cloud is pointless and bad? No, Somethings are just better suited for the cloud and having physical systems for them is counter intuitive. Tech progresses, learn to move with it, or be left in the past.
Also notice how I don't hide behind Anonymous coward?
