Numbers update in iWork for iCloud

Apple isn't letting the launch of Office for iPad go completely unanswered. It's pushing out a slew of iWork updates that might not keep Microsoft awake at night, but should fill in a few conspicuous feature gaps. You can now share read-only documents, for one thing -- you no longer have to worry that others will mess with a Pages report. You can also open iWork documents from iCloud webmail, and there's a host of cross-app improvements that include a new editor tab and the option of modifying imported charts. All the upgrades are available on iCloud, iOS and the Mac, so you can check out the many, many tweaks for yourself.
