CountMike, all valid points. But most will trade loss of overclocking capability if they can travel easily with their laptop. I like being able to move the laptop around the house, and take outside and sit on the porch.
And that's why I have both laptops, desktops and tablets Parks. Add to the mix a portable hard drive or three, and I'm all set to go traveling. When I'm going to be closer to home, I'll take one of my tablets with me. And, yes, I know that not everyone can afford some of each but I've been lucky. I do tend to keep stuff longer since I'm retired, though.
I'm not much of an upgrader, I just end up replacing the whole thing. Then I give the old one to my kids or somebody in need.
I'm lucky in that most of my desktops (except the current HP) were built long ago and upgraded as needed. A mobo here, RAM, there, video card another time, etc. I've retired several beta systems over the years and have had no problem finding someone of the senior persuasion who would like to upgrade.
Yep, my castoffs are an upgrade for some!
