I plan to. My reason is you just never know what could happen with the "cloud". If I need to re-install them on my iPad2 or iPhone4S or install them on my iPad 4 or iPhone6 and the cloud's unavailable for some reason, I wouldn't want to go through the hassle of re-downloading all of them one by one. I realize this scenario isn't that likely but that's just my personal reason. And I'm down to 3GB on my PC, but plan to keep all my apps and music on there anyway. Boils down to whatever you're comfortable with I guess.
