id been using Quickoffice to edit word docs on my ipod but was frustrated by the inability to open attachments in email. Well finally docs to go is here!!!! has much better interface, allows landscape AND uses the autocorrect which quickoffice didnt. But most importantly it can sync not only with pc/mac but also with a microsoft exchange mail account which finally allows opening and editing of mailed attachment. Doesnt have support for editing xls yet (only word but in 2003 and 2007 format). Apparently excel is coming in an update. This is without doubt the best productivity app ive purchased.
