Look for a digital organizer...
In short, the Palm Pilot was a line of PDAs made by Palm (now defunct) in the late 90s, and PDAs in general are no longer manufactured as most desire smartphones. Even at their prime, smartphones rarely had physical keyboards. However, personal digital organizers, such as this one, continue to have a place in most electronics stores and are sold in the $10-$50 range. They're very basic, but they have the advantage that the do not 'break the internet.'
Hope this helps,
