I can hold a tablet on the couch after a long day. I can rest but still go on Internet. I do not believe it is either a one or another replacing device. It is both for people's lifestyle. That's my two cents anyway.
I am speaking from living with the two devices.
In terms of growth, the pc is dead. Microsoft really missed the boat on tablets. The tablet market will grow while th pc market will stay flat. I indeed have both a pc and a tablet. While the tablet is fun and ultra easy, i still need my pc for intense programs such as photoshop and other photo processing programs.
sent from my TRS-80, expect errors.
My experience as well.
What has changed for me is that I use my desktop less than I used to. But who wants to do video editing, programming, web development or serious word processing on a tablet? Not me, I use my desktop for that.
But for checking in on FR and looking for a good Mexican restaurant on the road or in my easy chair my iPad is simply the perfect device. For me at least, my tablet and my desktop are both here to stay.
