^ that mouse looks horrible and gimmicky :/ like those troll mice they sell that's shaped like animals.
The amount of misinformation about Synapse 2.0 is ridiculously astounding. It amazes me that people's reading comprehension is so low that they can't interpret clear information properly, so they trust what randoms on the Reddit spread.
Synapse 2.0 is made so they don't have to increase the size of the memory on the mouse for all your 5-6 profiles. High speed memory is really expensive, so imagine the costs added onto already a large investment.
If you install Synapse 2.0, it's like having the Razer mouse drivers installed, except when instead of storing all the 6 profile settings on your mouse with expensive memory and swapping which profile the mouse uses, you link it up to the Internet and if you want to switch profiles, it'll download the profile from the Cloud and swap out the old profile into your mouse.
Sure, it can be used as a cheap way to monitor some of their user's preferences, if you let them track your information, but that's in no way the only reason.
i.e. People are foolish and need to learn to interpret information properly.
I'm pretty sure if it's just my upbringing, but I try to question and understand what I'm reading. I'm taking Engineering courses and they drilled into us that high speed memory is expensive. Think about how much cache is on your CPU, and how important cache is to your system.
