I'm trying to figure out how best to incorporate a Mac (would be my first!) into my existing computer setup. For work I'm stuck with a Dell laptop which I must travel with as I work out of various offices, my home office, and travel a bit. Desktop at home is an acceptable Dell desktop P4 running XP which I use for file downloads, torrents, iTunes, disc burning, basically anything I don't want to use my work laptop for. When working from home I dock my laptop and use a KVM to toggle between my work laptop and desktop. So... I've been considering buying a refurb Mac - MacBook Air (yes, I've read all about the issues), Macbook, Pro or a Mini. I would really like the portability, just not sure if I really want or need two laptops. The MBA might be perfect to carry around WITH my work laptop... seems light enough. I really want to keep it under $1500, but I know going MacBook Pro would stretch that. That $999 MBA is awfully tempting. How do you guys incorporate your Macs with your home and work PCs?
