I used my office as an extreme. One that I knew the bounds of. Sure, I support thousands of people as well at work. Lots of them user iPads or android tablets. I don't have numbers for them. But, a lot of the ones I actually talk to... prefer it over their computer. It's people like you that actually make it worse. You intentionally recommend people buy inferior products, worsening their opinion of the form factor as a whole. Also, making fun of people tends to piss people off regardless of whether you're right or not. Tablets aren't for everyone, not everyone needs one. Tablets also don't need to be purchased every year. So yes, sales should decline with market saturation. It should, however, stabilize at a level that covers a normal upgrade cycle.
