A bit about Lenovo
Lenovo is one of the largest producers of computers since its acquisition of IBM's branch of personal computers in 2005. Producing laptops under different lines such as ThinkPad, Yoga, Legion and IdeaPad. Along with 2 lines of desktop computers.
Lenovo has maintained the IBM quality and added a few new lines, with enough options to allow for ample choice-making depending on individual needs. The original, the ThinkPad, the line that is the only certified laptop for use on the International Space Station. The ThinkPad is a remnant of the IBM brand, a reliable machine built with office needs in mind. ThinkPad's are developed to last, have good all-round connectivity and performance. Models from this line have been considered some of the best business laptops over the years. The features vary between the models but options include touchscreen, 4K display, 17-hour battery life and more. There are versions that are built with harsh environments in mind as work doesn't always mean a desk, it could be a drilling site out in the desert. A dependable machine overall.
The flagship laptops from Lenovo are under the ThinkPad T Series, which usually have high-end features and build quality. They are tested against 12 military-grade requirements. The batteries on the newer models last up to 17 hours. The ThinkPad X Series is the more sleek version of the high-end machine, making them ultraportable. ThinkPad P Series are the more heavy-weight performance laptops geared for designers, engineers, architects and animators. For a slight budget advantage, there is the ThinkPad A Series, with professional capabilities. Moving down the scale some more the ThinkPad E Series is for mass-market requirements of smaller businesses, with a distinctive design form. With the ThinkPad L Series there is the advantage of being slightly more rugged, not as much as the ThinkPad T though. The L Series is a mid-range laptop, again geared for a work environment.
Lenovo has a broad range within the ThinkPad line; well thought out with variations of performance, sturdiness and price range. Which you decide to purchase is a matter of budget and requirements regarding your usage.
