1: iPad has office software, which can realize the common functions of Microsoft office. Although it is not the company's software, it is compatible.

2.2: iPad seems to have an adapter, but it is expensive and unnecessary! And there is no direct reading and writing software. I send the files I want to use by email.

3.3: Ipad can use the iphone version of the stock software, I use a straight flush, you can trade. Futures have never been used, and mine has never escaped from prison.

Practical experience. . .
