For Google, one of the changes it already has made is a redesign of the Gmail interface on the Apple iPad.
"When you write an email you’ll now get a big full screen compose window instead of splitting the screen between your inbox and the compose view," Google says. More text is visible at once and there are no more distractions with messages on the side.
As with adaptations made to format content and navigation for smartphone screens, it appears Google already has made adaptations of the email-compose layout specifically for the iPad form factor.
For application providers, all this suggests a possible need for a "third" way to format web sites and applications, including different rendering for large PC screens, small mobile phone screens and mid-size tablet form factors.
