Hah, well said! Bubs+ :)

But what he wasn't wrong in what he said, and your analogies are actually quite poor.
A phone is used for making and receiving calls and text, whereas a camera is used for taking pictures. 2 very different things. A camera app for a phone allows the phone to capture images. However, a tablet is just a portable, touch screen PC, though, it is not as versatile as a PC (full form i.e. desktop, laptop).
Will Windows 8 make my PC touch screen? No. Will Windows 8 make my PC (desktop) portable? No. So what he said, made sense. But your argument against did not. If you had said something along the lines of Windows 8 is a much more optimised OS which allows faster boot times and general speed increase, then it would have made sense, and I would have probably backed you up.
I apologies for the technicalities. But this is a tech site, and I am a techie. Peace.

Everyone knows Windows 8 won't make your PC touch screen. Adding a touch screen monitor will help in achieving that. Did adding a camera app for a phone turn the phone into a camera? Nope. It needed a compact camera added. Just as a touch screen needs added. I would have thought a techie would know an app wouldn't magically make a phone into a camera without an actual camera lense anywhere on the phone.

Also, I never said whether or not what he said makes sense. I'm basically saying he is a complainer of things that are new or different from the norm.

Your technicalities are quite poor for being a 'techie'. :)
