Lets see what do we have so far:
* A [[http://writely.com|word processor]]
* An [[http://meebo.com/|instant messenger]]
* A [[http://tadalist.com|todo list]]
* A [[http://basecamphq.com|project manager]]
* A [[http://www.protopage.com/|generic scratchpad]]
* A [[http://bloglines.com/|RSS aggregator]]
* An [[http://kiko.com|online calendar]]
* Ofcourse [[http://gmail.com|email]]
* and [[http://del.icio.us|bookmarks]]
* and [[http://www.backbase.com/|many]], [[http://www.ajaxian.com/|many]], [[http://www.techcrunch.com/?cat=97|more]]
Now all we need is a good replacement for photoshop, powerpoint and excel and integrate them all together into a single portal (Yahoo? Google? M$? other takers?) and there you have — your online desktop!
Of course, easier said than done. But things are moving fast. Very fast.
