The long awaited Quickoffice has finally hit the App Store (itunes link $19.99). The iPhone has been lacking a solid package of applications to easily view and edit Office documents and Quickoffice fills that spot nicely except for a few major flaws.
The Good
Quickword is nice and full-featured allowing you to create and edit word documents with the features you'd expect like copy/paste (even between documents) along with formatting options (font sizes, styles, etc.).
Quicksheet while a little laggy renders Excel worksheets well and includes a whopping 125 functions and formulas to handle most of your spreadsheeting needs.
Quickoffice File is just excellent when integrated with MobileMe. Simply drag files to your iDisk and bam they are editable on the iPhone.
The Bad
Where did predictive txt go? The iPhone keyboard can be difficult to type on and the built-in predictive text feature really should be working in Quickoffice.
Copy/Paste is missing from Quicksheet.
