Two different technologies that solve two different problems.

1. Tablets, etc. are for internet content consumption.

2. PCs are for content creation.

Try to create one of the following with a tablet:

1. A Gangnam Style Parody video.

2. A Word document.

3. A spread sheet.

4. Music editing.

5. Intensive photo editing.

you get the picture? ;)

HA

Nope.

I don't think that the attraction of sheer computing power that comes with a desktop computer can every really be outweighed by the portability of a tablet computer.

Laptops, maybe. They definitely couldn't replace a good alienware laptop, But probably could replace a less powerful notebook computer. But laptops aren't going to go poof anytime soon I think.

Until you can use Word on a tablet they wont be replacing anything, I wouldnt be surprised if tablets got smaller and phones got bigger and replaced the smart phone similar to what Samsung did with the Galaxy Note

Laptops and PC's have keyboards and a mouse, therefore you can operate it with both hands. When it comes to a tablet you're nearly always holding it with one hand.

An iPad can replace a laptop because the battery life lasts an estimated 10 hours. Neither a laptop or an iPad can replace a desktop computer.
