In the hustle and madness of yesterday's wayback machine activity, there were a couple of App Store introductions (and a notable upgrade) that might have slipped through...

First up: The long-awaited version of Quickoffice for iPhone that allows editing of Word and Excel files hit the store today and was demoed at CTIA. [Looks like the new Quicksheet is available now, but the full bundle and the Quickword standalone app aren't on sale yet as of Thursday morning.] While QO has had a 'mobile files' tool on the iPhone for a while now, this is the first build of the venerable portable office suite (which has been a favorite on Palm handhelds for years) that can do editing in both formats.

Quickoffice for iPhone can do font formatting and cut, copy and paste within Word documents -- presumably to be tied in with system-wide C/P in the OS 3.0 world-to-come. Both the Excel and Word tools will support landscape mode for extra editing area.

Files on the iPhone can be transferred off the device using WiFi to a local Mac, or straight to a MobileMe account. Quickoffice for iPhone is shipping now for an "introductory price" of $19.99, but if you just want the Excel spreadsheet editor (formerly MobileFiles Pro) you can have it for $12.99; the Word document editor is also $12.99. Quickoffice Files (previously known as MobileFiles 2.0) is $3.99 and offers similar file transfer capability to Readdle and other file managers. We're getting a review copy for a more thorough walkthrough later this week. It's worth noting that a Microsoft exec hinted at a version of Office itself for the iPhone that may be coming sometime in the not-too-distant future.

Second... who doesn't love a good robot game? For $4.99, you can now dive into Pangea's classic Otto Matic series with the company's new title for iPhone, Otto Matic: Alien Invasion. The B-movie style game pits Otto against the attacking Brain Aliens from Planet X; his job is to save as many humans as possible. Otto Matic: Alien Invasion features 10 levels and 25 different enemies, multiple weapons and activities, and quite a bit of fun.

Lastly, the TUAW top pick Evernote has been updated with a nifty landscape mode, thumbnail viewing, improved performance, favorites sorting, and an embedded web browser to reduce the tap a link --> Safari --> back to home screen --> scroll around --> relaunch Evernote loop-the-loop annoyances. Evernote 2.0 for iPhone remains a free download, and the basic Evernote service is also free; a year of pro-level service costs $45.
