I used to have a cordless Craftsman drill/light set that I loved, then the batteries inevitably died. I shrugged off cordless tools for years, but recently went back. With Li-ions, it seems that the battery packs should be easily rebuildable.
I've got too many corded tools, so my decision isn't generally choosing between cordless or corded, but rather deciding whether adding a cordless version will help me. My metric is that cordless tools are useful for short jobs where reducing the setup time helps (eg pick up a driver and use it). Corded tools take less maintenance and are adequate for jobs where you're already setting up a work area... which is most things involving a jigsaw. Not having to manage the cord during long cuts would be nice, but doesn't seem like it would make any task significantly easier. Then again if I didn't already have 2+ jigsaws I'd probably feel different.
