The original commentary is still valid!

Overall, the two this blogger enjoyed/used/liked the best are now (unfortunately) obsolete. Although at the the time they were the best on the market, their manufacturers did not upgrade them or come out with new and improved versions, and so they are fading away... (the present tense is used deliberately, because there are communities that still use, tweak, and keep them alive!). The productivity gold goes to the HP 200lx, and the silver to the Sharp SL-Cxxxx series.
