I like to keep my computer on all the time. It's more convenient and I can check my e-mail throughout the day. I can also keep up with the market although lately that hasn't been too pleasant.
It seems that this summer a lot of thunderstorms have been predicted for my area. This means that I have to shut down and disconnect my computer. I've been very wary of these storms since my TV and water pump were hit by lightening in my other house. I'd hate to lose my computer and all its memory.
I know people in other parts of the country have it much worse and I guess I'm spoiled, but it's annoying to shut down every night and whenever I'm away from the house. And then we never get the storm.
