iPhone can read Word, Excel, PDF documents

The title explains it all: Revealed in Apple's new iPhone Guided Tour video is the swanky handset's previously-unknown ability to read Word, Excel, and PDF document e-mail attachments. This alleviates fears to the contrary, and will sure be useful for those business-types On The Go eager for their quarterly profit reports and sweet pie charts and whatnot. But without actual editing capabilities, those business-y people still have something to complain about.

Then again, does anybody actually edit Word/Excel documents on their BlackBerry? (Serious question.)
