What do I get for Hannukka?

I basically have a choice between some sort of lens for my Canon Rebel XT or Final Draft Pro (screen writing software). Both are expensive and will benefit me in different ways....

camera lens: right now I only have the standard lens and I need a telephoto/wide-angle lens to really shoot the type of stuff I want to (sports, landscape etc.)

screen writing software: I have a full version on my PC but only the demo version on my Mac. I rarely use my PC anymore so all my writing is done on the Mac.

cash isn't an option. I'm 50-50 at this point. Do I go for the purely fun one or the one that will help me work?
