Palm
Treo 700w

By 2007, once-powerful Palm had no real operating system to call its own. Palm OS 5 was several years old and its successors, Palm OS 6 and the Access Linux Platform, were both deemed not good enough for retail by Palm. So the company shifted to the then near-dominant Microsoft Windows Mobile platform to power a business-friendly smartphone on the US's largest mobile network operator, Verizon. The Treo 700w used the form factor from 2004's Treo 650, which was well-regarded at the time and had a lot of goodwill. But the 700w somewhat awkwardly tried to shoehorn Windows Mobile, which preferred 3:2 screens, into a body with a 1:1 screen. It also lacked Wi-Fi and PC tethering, and tended to crash. It was a moderate success among corporate buyers who wanted a one-handed device that natively synced with their Microsoft servers, but BlackBerry and Apple had all the buzz in 2007.
