Final answer:
The major difference between a new tablet and a new laptop is that tablets have no field serviceable parts, whereas laptops often allow for component upgrades or replacements.
Step-by-step explanation:
One of the major differences between a new tablet and a new laptop computer is that A: a tablet has no field serviceable parts. Tablets are typically sealed units with components that are not meant to be upgraded or replaced by the user. In contrast, many laptops are designed with components that can be upgraded or replaced, such as RAM or storage. This makes tablets less customizable and harder to repair, but often more portable and with a simpler, more user-friendly design.
Laptops, despite having potentially more field functionality, do not necessarily have slower responsiveness than tablets. The performance depends on the specific models being compared. Moreover, tablets generally do not have faster Ethernet capability because most tablets rely on wireless connectivity and may not even include an Ethernet port.
