Ask HN: Why doesn't Google come up with Project Planning service?

Since we're using more and more web-based office tools like Google Docs/Spreadsheet/Powerpoint, it is still cumbersome to use other Project Planning services like Basecamp, etc and link Google Docs links there.

For Project planning, Spreadsheets and PowerPoint are still useful tools.

Why doesn't Google provide a complete suite for Project Planning which can have Docs/Spreadsheet/PowerPoint integrated in it?

Why there is no - Basecamp + Google Docs/Spreadsheet/Powerpoint integrated solution yet? May be Zoho is one...
