All sorts of online apps keep coming well, online these days. Some really useful, some are just time wasters, some are quite daft...

But I've come across this gem recently ie Google's online spreadsheet at spreadsheets.google.com. I didn't really check on the requirements for access but as long as you have a Google email account you're in. Just use your Google email address and password.

Of course it's not as powerful as Calc, Excel, etc but what do you expect from an online spreadsheet? It'll just get better by time, especially if it proves to be a hit among the users.

Have Google account? Go give it a spin!
