It's about that time when I have to decide whether to purchased my copy of iWork 08, or let my 30-day license expire. The original idea was that Apple's Pages, which runs native on my Intel Mac, could easily step in for the obscenely slow Microsoft Word. But since I can't save in word documents, I can only open and export them, it's not as useful as I might have hoped. But I rather like Numbers -- it's much better than Excel, from what I can gather. Is it worth $80 though? What I need isn't really a spreadsheet program, but a graphing device. And Numbers has some failures there. It's not easy to export graphs (in fact, I'm not even certain you can do it -- I take screenshots of mine), the graphs aren't as easily manipulable as I'd like, etc. So I figured I'd ask you guys before plunking down the cash: Is there dedicated, affordable, graphing software that's better for my purposes and runs on the Mac?
