one big problem that i have with bitcoin is difficulty, which will lead to this situation that i as an individual with a pc at home (no extra mining equipment) can not mine bitcoin, so mining becomes a business that a few (mining farms) can only do it.

can't say if it is all a bad thing, but i wished that mining of the cryptocurrency that is supposed to be decentralized could be done by anybody who wanted to do so.

Your post contradicts itself. You are talking about mining at home where you earn money; you can forget about that. You can mine at your home with whatever you want, but you won't be earning money. There's a huge difference and this can't be prevented either.

i can't suggest anything to Satoshi Nakamoto,bitcoin is perfect for me,even some transaction delay so long,i think its not happen many time.

Satoshi is gone and thus irrelevant at this point in time. There are no transaction delays; there are only confirmation delays because people don't include the proper fees.

Take out all the irrelevant text message capabilities. They fill up blocks with rubbish, and nobody is going to take a money transfer service seriously if it is full of dog obituaries and wedding reports.

That wouldn't be a censorship-free and decentralized system then.
