[ltp] Help needed with choosing the right ThinkPad

[tomtom at tutanota.com]

Thanks for all the replies so far!

To the questions about my requirements:
Well, I would like it to be considerably lighter than the T61 I have, be equipped with a full hd IPS panel if available, and more than 8 GB of RAM should be possible. And the overall performance should be good enough that I don't have to think about buying another one the next years. The screen size is not so important to me, the 12,5 inch of the X270 would be enough and the 14 inch of the T450s would still be good to fit into a backpack. If I do things that require a bigger screen size, I will work with an external monitor anyways.

In terms of budget, I found the two discussed models at around the same price, with the T450s a bit cheaper but with only 8 GB of RAM (with 4 soldered to the board). As it seems, upgrading it to 12 GB would be rather easy and cheap, but upgrading to 20 GB is rather expensive, as 16 GB sodimm ddr3 is rather rare and the prices high. Or does anyone know a good source for it?

12 GB would probably be totally enough most of the time, but I'd prefer to have the option to have more.

Apart from that, I'm wondering how big the differences will be performance-wise, but it seems like the the two models are rather similar with the offered (i7-5600U and i5-7300U) CPUs (?)
In terms oft ruggedness, I thought the X2x0 series is about the same as the T-Series, or is it not?

Thanks again for all replies!

> any thinkpad will run any form of linux perfectly. what model to buy depends on your budget. how much are you will to spend? what features do you want? touchscreens oleds cost more. imo stick with the business line the t series great value for money and bulit like tanks.
