But don't expect to use it to design computer circuit diagrams!
I've been to a real computer motherboard design company before,
and the software they used was all developed in-house,
there's no comparison at all with this!
Even more disgusting is that most motherboard makers directly copy VIA or Intel motherboard designs,
so they basically don't need any R&D at all,
they just make tiny changes in a few places!
Who told China's IT industry to be so backward!
That damn Communist Party,
it's harmed people deeply!
Do you know why Lenovo computers don't use garbage motherboards made by Lenovo itself?!
The reason is simple: the motherboards Lenovo makes cost too much!
And the stuff is garbage too,
so they can only let others do the OEM work!
The manufacturing cost is actually even higher than buying from others,
really hard to imagine!
