According to several customer reviews, the Lenovo ThinkPad T580 is one of the best business laptops to get in the United States, and after a hands on experience, it\u2019s hard to disagree. The 512GB SSD pairs perfectly with a great port selection, keyboard, and speakers. The only issues found are with the bezels and the need to upgrade, but other than that, the Lenovo ThinkPad T580 more than deserves to be at the top of our list for Best Ubuntu Laptop and the best laptop.\r\n\r\nWhy We Like It - Lenovo ThinkPad T580\r\nWith a moderately sized hard drive and quad core processor, the Lenovo ThinkPad T580 can be used for both work and play. To max out its potential, and upgrade to its battery life will make the ThinkPad last all day.\r\n\r\nPower\/Performance\r\nPowered by an Intel core i7 processor and 16 GB of RAM, the Lenovo ThinkPad T580 is more than capable of handling multiple tasks at the same time. Whether it be presentations or documents, the ThinkPad can load, process, and edit on the fly without stuttering or lag, reliable for when you need to edit on the go. With a performance that rivals the Dell XPS 13 9370, the ThinkPad T580 will last long throughout the day.\r\nBattery\r\nThis is where the Lenovo ThinkPad T580 gets some fair criticism. The included battery that comes with the ThinkPad is nine hours; not too bad, but compared to other laptops such as the Acer Aspire E 15, it feels lackluster. There is a solution however: getting a battery upgrade. If you want to get the most out of your laptop, you\u2019re going to have to shell out a few more dollars to do so.\r\nPorts\/Expandability\r\nThe Lenovo ThinkPad T580 comes equipped with a Kensington Lock, SD card slot\/card reader, USB C, Thunderbolt 3 slot, HDMI, USB and a Headphone\/Mic. An altogether fantastic port selection ready for anything you may need.\r\nBuild Quality\r\nAll around the Lenovo ThinkPad T580 feels fantastic to carry around. Constructed out of a plastic material, it doesn't feel cheap. The only negative thing to note is found with the bezels of the screen. Feeling a bit too big for the screen, the Dell XPS 15 9560 offers a more clear screen.\r\nValue\r\nWhat hurts the value of the Lenovo ThinkPad T580 is its insistence on gatekeeping the best performance it can give behind an upgrade. Of course people are going to want more battery life, and to not offer a model with said upgrade seems rather obtuse for Lenovo.\r\nLenovo ThinkPad T580 Wrap Up\r\nPerfect for productivity on the go, the Lenovo ThinkPad T580 can handle any assignment given to you and then some. With plenty of ports to use, a keyboard that won\u2019t leave you strained, and clear sounding speakers, the Lenovo ThinkPad T580 more than makes up for its thick bezels and needs to upgrade to get the maximum performance out of it. To those looking for a new laptop, the Lenovo ThinkPad T580 gives plenty of reason to consider using it.
