1, there is a pdf tagging software called xodo Docs, which is free and the software volume is not very large, so it is suitable for reading literature. It's relatively easy. It's not perfect.

2. There is also a pdf notes, which is suitable for 64-bit systems. I feel that the operation is a little more convenient.

3. The mail client uses the metro application that comes with windows, and it is enough to add common mailboxes. Beautiful interface.

4. Notebooks are onenote, which is easy to use and suitable for multi-platform * * * to enjoy notes. It seems that the support for edge browser is not very good. In the desktop browser and metro browser of the computer, I remember that there is a right-click function to send to onenote.

5. Wireless file transfer between devices. I think onedrive costs a lot of traffic, and I can't build a local area network. Bluetooth is slow. Later, Lenovo used a software called Eggplant Fast Transfer, and all devices connected to a router can transfer files conveniently. This software is stupid and the interface is good. I use the desktop version on both the tablet and the computer. There are also Android and ios versions and mac versions wp.

6. Version can be selected. The disadvantage is that when the device zoom ratio is set to 200, the interface of eggplant quick transmission will overflow the screen and the button will not be clicked.
