The Dell Latitude 14 5411 is not slim, but it is powerful. With Intel's Core i7-10850H and Nvidia's GeForce MX250, it can also be used for much more than just office applications. Our review shows what the small business laptop can do in everyday use.

This is probably one of the last business laptops to have touchpad buttons. With the Tiger Lake refresh, every single business laptop in the industry would have moved to crappy buttonless clickpads except the ThinkPads which thankfully retain at least the top TrackPoint buttons even though their touchpad is also a clickpad.
This laptop is available with Thunderbolt 3 but probably half speed 20 Gbps port because looking at this: https://www.dell.com/support/kbdoc/en-us/000060905/thunderbolt-3-40gbps-data-transfer-rate I am not sure about the number of PCIe lanes
Pascal-era GPU and mediocracy for 1700 USD is not a good bargain.
A tiger like pc can preform much better.
When 11th gen comes out if they can slap a thunderbolt 4 port on this and still retain the option without a dGPU I would be tempted. A high powered CPU with direct-to-cpu TB4 without a dGPU would be a great eGPU platform.
