I like to "putter"... so-so with building things, i.e. furniture, cabinets - but as long as you can give me directions I'm usually OK. Electrical stuff, i.e. wiring outlets, etc. about the same - fine as long as I have a manual or a book.
Much better with electronics, esp. computers - going back when you had to install all the software and format the hard drive. It's so much easier now... but once in a while I'll get out on the DOS prompt just to experience the "good" old days...
Can hookup cable, VCRs, DVDs, receivers pretty much with one eye tied behind my back - also pretty handy at formatting/programming electronics as well. I used to be a real sucker for technology - unfortunately it's been going so fast I'm at least 5 years behind (still haven't gotten an ipod or player yet).
Plumbing tho' is a mystery... I usually yell for my Dad or hire someone else to do it.
