I love spreadsheets. So much so that I even mentioned Excel in dating profiles. But Excel is expensive, OpenOffice slow and buggy, and Google is... well, Google. Ethersheet is a fast, effective, and reliable alternative to get your spreadsheeting done. I love spreadsheets and so I love Ethersheet. If you're like me, you will, too.
FYI you can rent Excel, Outlook, Word, Powerpoint, OneNote, Access and publisher for three beers a month at London prices. That's pretty cheap and it works online and offline.
