How accurate is the wireless mouse/keyboard?

Question

Keyboard

I'm going to buy a Logitech wireless mouse + keyboard kit for my macbook, please tell me if it's worth it or wired devices work more accurately. I just often work with Photoshop, I need high accuracy. Never used wireless devices :)

Answer 1

The accuracy will be exactly the same. The lag is minimal if the receiver is placed closer (better signal), for example, on the front panel. I have them on my monitor.

Answer 2

Photoshop requires a tablet and a pen. Wacom is all that. No mouse will replace it.
The presence / absence of a wire will not affect the work in Photoshop at all, since it only affects the signal transmission delay and drives only in Starcraft / Dota / and online shooters.
Well, if you buy a kit for 200 rubles, then yes, there will be difficulties with positioning.
In general, a mouse, a keyboard is a purely personal choice, at hand, according to habits, I bought myself a keyboard for almost $ 300 and I don’t regret it, I won’t change it to something else for sure, I’ve been using Microsoft Natural Ergonomic for a long time, but I’m not small myself by oneself.
Of the mice, I like the Razer and Logitech Revolution series, now the Logitech Performance Mouse MX is similar in design to it, but I repeat - this is a purely personal choice.

Answer 3

Contrary to common misconception, wireless devices can not only perform the same, but also faster. This is due to the fact that when using a wireless communication channel, there is the shortest transmitter-receiver distance. Unfortunately, the number of wireless devices is so large that they make a lot of noise to each other today (and try turning on the microwave next to the bluetooth headset). Therefore, there are two things that slow down the transmission of a signal: hardware delays, signal distortion. In the first case, we are faced with the need to first modulate, then modulate, and on the other side, demodulate. And secondly: encode and decode (before modulation and after demodulation). It's not that simple, many error-correcting codes work with probabilistic ensembles of many trillions of elements (rather - the number of trillions of zeros =). And although they try to implement this as much as possible in hardware, in general it is impossible.
OK. Now, as far as accuracy, everything will be very accurate. Well, you won’t even notice the delay (the so-called lag) - there, if not nano, then microseconds. Bluetooth is a slightly different matter - due to the specifics of bluetooth operation, it guarantees the channel size, but not the response, which greatly affects the result - random delays greatly reduce usability.
