My Droid has two built-in calendars. One personal and one to sync with an Exchange server. It has two built-in email clients. One for GMail and one for standard protocols. It has a calculator and a clock. It has all the functions of my old PDAs, both Palm and PocketPC, except for a To-do list. Of course I can download over a dozen applications to fill that niche but you’d think it would be built in.
The iPhone fared no better. A coworker owns an iPhone. I asked if he had a To-do list built in. He did not. He had to get an app for it, too.
