Laptop. I have a Mac and love it, but others love their Windows 8.1 or 7. NOT Windows 8. I hope you found the advice you really need. :)
Of course, I meant to ping onyx to this. LOL! Ok, having a good laptop does not guarantee user expertise! :)
A friend loaned me her laptop while I gathered the money for a new computer after mine bit the dust.
.. it was like looking at a monitor through a backwards telescope while working the keyboard with a pool cue IMO.
But obviously, opinions differ.
