20 years ago when IBM developed the Thinkpad, portable computers looked....different. We spotted this one in a lineup of classic Thinkpad laptops we were shown recently - it's the Palm Top PC110, sold between 1996 and 1997. Even now, the Palm Top is tiny - around 15.8cm wide and 11.3cm deep, and weighing (according to the specs we dug up from various sources online) around 715g with a battery and hard drive. Exactly how users typed on the insanely tiny keys is our question. According to our information, the Palm Top 110 cost $3,000 in the US. Ouch.
