Using them for just a few hours I realised how bad they are. The screens were awful, navigation was horrible, the keyboard hurt the tips of my thumbs and they were slow. So so slow. I don't remember them being quite as slow so perhaps it is battery related (although they were plugged in) but it wasn't great waiting 5 seconds for an attachment to load when I am used to it being instant on my 3 year old iPhone.
I know we are spoilt now with HiDPI screens and stupidly fast mobile SoC's but they really were horrible devices looking back.
Perhaps language such as "horrible" is unfair but it is the adjective that first popped into my head to describe the experience.
