I have a tendency to spend a lot of time on the computer. We don't really watch t.v. so this is our substitute. However, usually, computer time involves some form of either work or play.
I've taken to keeping my drop spindle right by my computer. Anytime anything takes a bit of time to do (i.e. waiting for something to load up, or if I'm just reading an article online), I use the drop spindle. I have a knitting project usually by my computer, but the problem is that if there is a pattern of some sort, I have to pay attention to the knitting rather than what I'm doing on the computer. Sometimes this is not a good combination. However, I can put down my spinning at any given time and not have to worry about remembering where I left off.
This also means I get in a lot of little bits of time spinning in between projects. Now that I own a wheel, I realize that if I only had the wheel, I wouldn't get as much done. Don't get me wrong -- I *LIKE* the wheel. And, I'm getting a bunch of spinning practice done on it -- about 10-15 minutes a day. But, it sits in the living room isolated from most of the bustle of the household, which is nice when I want to get some alone time. It's a nice quiet form of meditation.
However, when I'm with DH or on the computer or on the go, it'll be the drop spindle I reach for the most -- it's very portable. And I know that plying will be more of a "breeze" on the wheel than on the spindle.
The wheel is going to get a lot of use; but I think the drop spindles are going to get much more used just because of my lifestyle.
