Quickword -- which is just like the $19.99 Quickoffice app but only contains the MS Word features -- is usually sold for $12.99. But the app is currently on sale, and the next 1,000 customers can get it for only $4.99. If you don't need spreadsheet support, then Quickword is a great alternative to Quickoffice, and at this price I strongly encourage you to give it a spin. My review of Quickword is here. My review of the full Quickoffice app is here.
Also, remember that today is the deadline for the discounted prices on DataViz's Documents to Go. If you buy today, you can get Documents to Go with Exchange support for $9.99, or without Exchange for $4.99. My review of Documents to Go is here.
I think that many attorneys will want the flexibility of having both Quickoffice/Quickword and Documents to Go on their iPhones, and at these discount prices, it is very affordable to do so.
