google spreadsheet

there has be a lot of press attention to the realease of spreadsheet application by google, but i guess many of us don't know a much better, functional, online spreadsheet tool (with can be added on your google home page aka. google ig) by: IROWS

i find it more usable because:
- has lot more features, charting support!
- right click works as in OpenOffice (i do not use excel)
- it can save & read in OpenOffice format!, google can read and write only .xls and .csv format

but probably these features will get added into google spreadsheet with time.
