Palm Treo was developed by Handspring, which Palm acquired in the early 2000s. Palm, one of the earliest makers of smartphones, was unable to follow up its success in the personal organizer business. The company was slow to realize that consumers wanted wireless voice and data from the same device. Palm couldn’t find the formula for over-the-air synchronization with Microsoft Outlook, which business users demand and RIM nailed with its BlackBerry device. Palm also suffered from multiple product delays.
