WorkOS is a modern identity platform for B2B SaaS, supporting SSO, SCIM, user management, and RBAC.
Charles Ying looks at Safari 4’s new interface for tabs and speculates that it’s designed for future multi-touch displays from Apple.
I disagree. Tappable targets on a touch screen need to be bigger and/or further apart, because finger tips are large, whereas mouse pointers are very precise. The tip of the arrow mouse pointer is precisely one pixel. Apple’s iPhone UI guidelines suggest that a typical finger tip covers about 40 pixels on the iPhone’s 163 pixel-per-inch display. So I would say Safari 4’s tabs would be worse than Safari 3’s for touch screen use, because clickable targets in the title/tab bar are packed closer together. (For this same reason, the entire Mac OS X interface as a whole is poorly suited to touch screen use — look at how close the standard close/minimize/zoom buttons are.)
