Trackball vs Mouse, How to Choose Trackball


Logitech MX Ergo Trackball was $100, now $75

hey @xah_lee have you ever tried this logitech? looks like the upgrade to the M570, but im not sure it is worth it anyone else feel free to chime it

it's very good. my friend @AenonSun uses it, and i tried it. i have a page on it but not much info Logitech MX Ergo Trackball i'd say it's one of the top 3, if i'd consider to buy a trackball.

wacom is actually a Japanese company. didn't know that. Now more respect.

do you have updated list of best ergo dream keyboard?

Hi Pablo, happy 2019! this list is probably the best one can get Best Ergonomic Keyboards 2019 as i keep watching the scene. Of that list, take off those don't have tenting. and take off perhaps the Microsoft one, and take off Mistel Barocco (cuz too few keys)

that list doesn't include Do It Yourself ones. cuz too many Do-It-Yourself Keyboards. Also, for those with too few keys, a perfect solution is to add a programable keypad. If one allow that, then Mistel Barocco would also be great.

oh, you mean which characteristics.

i see. i think it depends on each's preference. For me, it's this, more important first

  1. split hands (1 physical piece is ok)
  2. tented [see Is Keyboard Tenting Important?]
  3. 3 thumb keys per hand. (more is not necessarily better)
  4. full size physical F1 to F12,arrows,page up/down keys.
  5. driverless programable.
  6. rectangular grid layout.
  7. concave like kinesis

best usb drive?

other usb drives are $30, this one is $80. Actually i think i trust this. Look at its reviews with the usb test result by users.

HyperX Savage128GB USB Flash Drive 3.1/3.0 350MB/s R, 250MB/s W (HXS3/128GB) Buy at amazon

by the way, expensive no mean good. there are lots tech gadgets that when the model's no longer made, their price goes up. this includes laptops. Some item's price go up cuz people really want them. e.g. Microsoft Trackball Explorer . But now i've seen price went up due to ignorant confusion of models.

and here's others that seems to be best.

Samsung MUF-128AB/AM FIT Plus 128GB USB 3.1 Flash Drive Buy at amazon $30

Kingston Digital 64GB DataTraveler Elite G2 Buy at amazon $29

gadget review site wiredcutter, seem just for ignorant consumers. I looked at their ergonomic keyboard review, meh. I've now looked at their usb drive, drawing tablet, bike lock. Only the bike lock article seems good, but am ignorant there.

don't buy Logitech C920 webcam

Buy at amazon BAD. All the review sites say it's best. I bought it. It has problem focusing correctly for anything within 50cm. It can focus correctly if something is really close, like 5cm, but when you bring somethnig close, such as a keyboard, within 50 cm but not as close as 5cm, it tries to auto focus but its final choice is blurry. Lots 1 ⭐ review have similar complaints. Also, the other model C922x, isn't better.

Right now (2018-12-19), am not sure what other webcam to get.

Ultimate Hacking Keyboard

i posted to reddit https://www.reddit.com/r/MechanicalKeyboards/comments/a6f6x5/ultimate_hacking_keyboard_review/ but seems the post is being blocked. Shadow ban?

i posted another, only picture without link https://www.reddit.com/r/MechanicalKeyboards/comments/a6fz7c/ultimate_hacking_keyboard_review/ and that seems to work

quick answer on reddit:

very impressed by it.

  • Solid build
  • The software to set the keys is the most intuitive i've ever seen.
  • Offers advanced program capabilities for the keys. unlimited profiles, macros, dual purpose keys (e.g. space as control ), and config can be exported/imported for sharing. Any key can be mapped to any function. e.g. afaik, you can have every key act as dual function keys. (for those familiar with QMK of ergodox fame, while i never used, but as far as i know it's UI is really bad, like the way one'd spend hours with linux. The UHK's software, called agent, is GUI and extremely intuitive. and it's open source too. Apparently the keyboard design is also open source.)

The software/firmware, especially the hardwired dual function key is the best. 32k memory.

also, it has addon modules for trackball/trackpoint/touchpad, attached to the thumb area. This seems a killer product, which would be very rare among DIY. But they are not out yet.

i'd now place this among the top 3 best. (not counting DIY ones, since there are too many) And among compact ones, i consider this the best.

best keyboard for traveling

Hi, How are you?

Can I ask a quick question?

As you know, I am using a Microsoft Sculpt keyboard. I have three of them for office, home, and even traveling or any other cases.

It is a bit bulky to carry, but I cannot use my laptop keyboard anymore. It is so tiring.

MS sculpt KB + Xah Flykey are my savor for daily work.

it's hard to say which is the best for traveling.

i think one of the following might suit your needs:

i'd favore the kinesis Freestyle Edge if you don't find it too bulky.

x-bows is great except it isn't split, and is flat.

Mistel is good except it doesn't have physical number keys and no F1 keys.
