Apple's biggest feature is that the battery is always more durable than other brands, and the performance of the battery will be upgraded every time the version is upgraded.
At present, it seems that Apple's system should still be Snow Leopard, and the gap between Apple's system and windows is still quite large. First, Snow Leopard is a real 64-bit system, while non-windows64-bit also hides a 32-bit kernel, and then it is said to be backward compatible with 32-bit software. Second, the Apple system only needs one partition, unlike the windows system, which is divided into one partition and then into other partitions. Apple only needs a common partition, which is much more convenient. The method of installing and uninstalling software is also much simpler than windows.
In short, Apple will give you a brand-new user experience. In the end, whether you like this experience or not is your own business. Some people don't like to change the way they used to, while others will like it gradually.
