Hi this is Stevie. It depends on how you type. I have been using both for a while, and love them both. I love the sleekness of Touch Cover. Touch Cover has a very special digitizer that we invented.. it senses the impact force of your key presses. We designed super-fast electronics and smart algorithm in the keyboard so that Touch Cover can profile your key press down to a 1ms (1000 times a second). Using that information Touch Cover can infer if the user meant to press the key or not.. It is a smart key. So even though there is no key travel, the user can rest their hands on top of the keyboard and find home position without accidentally triggering keys.. pretty cool! The first time I typed on a full working version of Touch Cover, I typed just as fast as I do on a normal keyboard. I am confident you will be able to type significantly faster on Touch Cover than an onscreen keyboard. And with a little practice you will even do better (maybe even faster!) For folks who really love and really need keys that have travel, then Type Cover is one of the best keyboards I have ever used (desktop or other). It has a super awesome snappy key mechanism that feels great (has a strong hysteresis curve). Honestly both are great
try them both, actually get them both.
