I received a X270 as a replacement (I had the my T460 stolen while on vacation in Malaysia) at my workplace, and prior i have used the X230/T440P/T450/X240/X250.
I have noticed the following,
The cons and issues
1. The device gets uncomfortable warm on the left side where the fan vent is, and may not be suited to use on the lap when it reaches such temperature
2. When connected to power, even when there is very low load (under 50%), the fan kicks in and is audible
3. The new touch type finger scanner takes some getting used to after years of swipe type scanners ! I am not sure if its me, but i felt the touch scanners seem to be more efficient at recognizing.
4. Battery life is not as great considering it has two batteries, i have the extended type
5. The machine came with the low spec 1366x768 display, i have no clue why Lenovo continues to offer these low end displays because it effects productivity. As long as vendors offer these low end displays and mid level business, IT procurement units will by them with this crap displays to keep cost low (since the procurement team rarely looks at productivity), and the users will loath the device when in truth its not an issue with the laptop but the fact that it was purchased with a low end display
6. The X270 continues the lenovo strategy, business users don't need good speakers (duh! we do listen to some music at home or late at work, and the speakers seem only good for a voice conference purposes)
7. Our machines are locked down (USB blocked, etc) and the fingerprint scanner did not work without our network admin having to resort to registry hacks (seemingly something is different with this fingerprint scanner).
8. Only 2 USB ports (yes there is one USB-C) but it would be nice to have at-least 3 USB ports
9. Externally there is very little to notice on this compared to the X240/50/60. Lenovo surveys must have told them the design is not to be tampered with, or maybe the existence of the Carbon series means no innovation on design for the X-series)
The goods
1. Touchpad is great
2. Keyboard is great
3. General performance is decent (mine was configured with an i5-7300U, 8GB and the samsung SSD, and one has to expect it to perform!)
4. Web cam is pretty decent in good light
5. Matte type display and the display brightness is adequate that you can work without any reflections or brightness issues outdoors and indoors
