I received my TREG unit last week and have been exclusively using it at work. Put my old keyboard in the drawer figuring I would jump in with both feet.
Here are my quick impressions after about two days of use. I won't go in to the packaging, quality, etc. since that's all been covered and it's all accurate.
Coming in to this I felt a little cocky. On the apple keyboard that came with my iMac and on my 2010 MacBook Pro I could accurately type 75 to 80 wpm and had mostly good form, using pinkies correctly, etc.
Typing only letters without caps, punctuation or numbers I could almost match my previous speed within a few minutes. I made a boundary layer adjustment and I was good. Only thing that still throws me off a little is the letter M. Apparently I always used my middle finger to strike the M key and the TextBlade forces you to use your pointer finger.
However, as soon as you throw in caps, numbers and punctuation... oof. With only caps I can manage 50 wpm with high accuracy. Add numbers and punctuation and that plummets. You definitely have to make a commitment to re-train your muscle memory for punctuation. You also need to commit to learn to use both the left and right shift keys since you can't type capital Z, A or Q with the left shift key.
The other part is just memorizing all the chords for the green, edit, select, app and media layers. For this I created a custom map, made a couple small tweaks to suite my preferences and then used the awesome PDF legend feature. Creates a PDF with a legend for all the layers (with any customizations you have made) that you can print out on one page which I keep in front of me. I imagine within a week or so of all day use I should have everything memorized.
There is definitely a lot of power in the layers. I know that once I have everything memorized I will be able to edit through a document quicker than before.
I haven't tried going back to my old keyboard just yet. Will post again when I try that.
At this moment my feelings are that if you travel for work, work at a coffee shop/cafe, are a student and don't want to lug a laptop with you everywhere or take a lot of notes at meetings this is a no brainer. You won't regret buying the TextBlade for a second. It's straight up quality and does what it sets out to do with excellence.
If you primarily work at a desk then this is very cool kit. But you have to be willing to make a time investment to learn how to use it fully in order for it to be worth the switch. Of course if you're a gadget nut like I imagine most of those here are, then it's worth it in it's own right. But if you don't have a real need for the TextBlade and you don't have the patience for new tech then I can see this ending up collecting dust in your drawer.
This opinion may shift over the coming days and weeks. I'll post again soon.
And yes, jumps are awesome! Implemented very well with a little key buffering so you can start typing almost immediately and it will transmit what you typed as soon as the connection is fully established.
That's it for now. Will post again in a couple days.
