The L Series is close to the T series, but even the T series has gotten quite beastly (size-wise) since the T6x/z6x series and worse over time. It's unfortunate that Lenovo seems to have squandered the once "Cadillac" mystique of the ThinkPad brand-- so much so that the vaunted IBM now looks elsewhere (I think also since they are embracing Fedora OS in lieu of Windows, as well, but I digress).
To get to the sveltness of the T4x series, had to pony up for a T4xxS and now a T4xxU.
Yet, this is still a notebook, however and it does share most of the construction qualities that make a ThinkPad a ThinkPad (magnesium alloy chassis with "roll cage", spill resistant keyboard, HD shock sensor, ThinkLight, etc), but you will sacrifice features compared to a T series or a mid level offering from another company such as Asus or Sony: worse screen, middling processor, weak graphics, and unspectacular battery life, and portability. I don't know if the L series are dock-able or not.
What's the point of a signature? Everyone can see who wrote this, over there, to the left.
