I have skipped vista and win7 but I think my new PC will be a win8.
I'm still running XP on a laptop that stays connected to a 24" monitor and external keyboard/mouse (I used to move the laptop between 2 offices, each w/ the same monitor/kbd/mouse).
Sometimes it's nice to use my wife's iPad if I'm not in my office (it's never worth moving the laptop), but it would make no sense at all to get another iPad.
Like Mouser, I'm thinking of jumping from XP to Windows 8 (I'm a slow os adopter, moved from OS/2 to XP in 2003). I'm also going to have to bite the bullet and upgrade Word & Excel 2002, so I might as well think of a big jump there too.
So I'm thinking of getting a Surface tablet, using it as a tablet on the porch and plugging it into my current office setup to learn Windows 8 and Office 201n.
Someone offered to buy me an iPad, but I declined since it would have been a waste of money. But I imagine the offer would extend to a Surface Pro.
