I had two BlackBerry devices for work, right about the time they were going away. I’d heard the keyboard was good on earlier models but it seemed like the quality had gotten pretty cheap on the later phones. The BlackBerry 10 OS on my last phone was actually pretty good, and probably would’ve kept them in the market if they’d launched it 5 years earlier.
Others that fit description were ATI Techologies (now the AMD graphics card division that makes Radeon) and Nortel networks, a maker of corporate and commercial telecom gear (including hardware routers and firewalls).
