I just signed in to the new Google Spreadsheet and am impressed with it so far. Since Apple’s own iWork ‘06 lacks a full spreadsheet, the Google Spreadsheet might be a good complement to iWorks when connected to the net.
FYI: I don’t use iWork. I got Microsoft Office 2004 for the Mac to work easier with not only the vast number of existing Office users but with myself when I use Microsoft Windows (often). I’ve tried NeoOffice/J and OpenOffice (X11) in Mac OS X and wasn’t quite satisfied with those solutions. Google Spreadsheet’s AJAX-ified interface seems pretty responsive on my MacBook. It seems to have a rich function list. And, its ability to share a spreadsheet on the web with just a couple of clicks looks very interesting. I might start using it to track my iPod nano menu/music reset problem :-)
