The Limits of the iWork for iCloud Beta

Apple has posted a support document, Size limits of iWork for iCloud beta documents. Among other interesting facts provided by the document are these: the iWork for iCloud beta can share a document with as many as 100 users at a time, an iWork document can be as large as 1 GB (though a few such documents can use up your iCloud storage allocation quickly), and each image in a document (JPEG, PNG, or GIF) can be as large as 10 MB (except in IE 9 on Windows, where the limit is 5 MB). Also, in Numbers you can create as many sheets as you like, and change as many as 100,000 table cells at one time. Furthermore, tables can have as many as 255 columns, 65,536 rows, and 130,000 data-containing cells.
