Hope it helps!

I'll be you one by one.

First, the T you mentioned is ThinkPad, which is a brand owned by IBM and was acquired by Lenovo in 2005.

Second, what computer you want to buy depends on what you need. If you pursue low power consumption, portable and fashionable, usually watch movies and listen to songs, and don't particularly care about performance, then consider ultrabooks, and 3500 to 4500, the performance will not be too good, go to the low-configuration version of the Yoga11S series, or the U410 series. If you need to play some large-scale 3D games or pursue relatively good performance, don't buy an ultrabook, consider your price point, go for the G400 series, which is inexpensive and practical.

Which specific model, you can consider it yourself, and you can ask me if you don't understand the parameters. Hope.

Lenovo notebooks and ultrabooks both have their own advantages and disadvantages:

The advantage of the ultrabook is that it is thin and light, easy to carry, and is generally used in the office, but the disadvantage is that it is too thin and light, and the heat dissipation is poor, which is not suitable for entertainment and games.

The advantage of general notebooks is that they have good heat dissipation and can be used for entertainment games, etc., while the disadvantage is that they are too bulky and inconvenient to carry.

Laptops, also known as "portable computers", are characterized by their small size, which is easier to carry than PCs. A notebook computer, also known as a laptop, handheld or laptop, is a small, portable personal computer that typically weighs 1-3 kilograms. The current trend is to be smaller and lighter, but more powerful.
