I love mobile phones. My first mobile phone is Samsung S4. Since then, I have used Xiaomi Mi2, Honor 7, Huawei Mate 9 and Huawei Mate 20 Pro. Similarly, I also love to write articles about mobile phones.

    1. Jack,
      Lenovo, just lowered the price on these Thinkbook laptops. I’m sure Lenovo is clearing the decks for updates to the latest 10th generation processors. The 14s with Intel I7-8565U processor 8GB ram and a 256GB SSD is on sale on the Lenovo web site for $599. That’s a heck a deal. I also noticed the 14s with Intel I5 processor (selling at $506) is out of stock.
