It&#x27;s a bit like the vi&#x2F;emacs debate, it&#x27;ll run and run :)<p>I prefer mechanical keyboards - my old IBM Model M that is wearing better than I am, or on new keyboards, Cherry MX Blues.  I&#x27;ve no doubt that colours my laptop preferences.  TP keyboards tried to duplicate that feel.  Lenovo have slowly backed down the IBM &quot;clicky&quot; feel of the keyboard so a t22 or t43p feels quite a bit more clicky than a W520.<p>@masseyset says the new keyboard has better spacing.  What he means is the key spacing is <i>precisely identical</i> (I saw many reviews claimed larger spacing, or that the keyboard was bigger, it&#x27;s objectively untrue) but the key tops, being flat rather than sculpted, are larger so feel like a different spacing.<p>Being chicklet, the key travel is a fraction 1&#x2F;2, 1&#x2F;3? of the old TP keyboard.  This is the bit I hate with chicklet keyboards along with their actuation point.  6 or 8 years of Macbook as main machine and I never got past that dislike.  Devoid of feel and travel.  I ended up with a Matias Tactile Pro for any time I wanted to do anything significant, so only needed to use the dead calculator keyboard when travelling.<p>The Thinkpad chicklet keyboard is way ahead of a Mac or anyone else&#x27;s chicklet keyboard, and they brought back a fair bit of the clicky feel they&#x27;d slowly been losing (at least on my friend&#x27;s W540).  As chicklets go, it&#x27;s very good.  It&#x27;ll never have the travel of the old 7 row TP keyboard, so I will never like it.<p>I could probably live with the new TP chicklet as the weighting is back to good.  The lack of travel and scattering the pgup&#x2F;home block randomly around the whole keyboard to save 50c and the extra 1&#x2F;2 row is unforgivable.<p>I think that covers my biases.  Oh, I lean towards vi. :)
