It has similar spec to my current broken laptop. Instead of a i5, it comes with an i7 8550U, 8GB of RAM and 256GB storage. It is a renewed product, by the way. And it goes for around ₹24,000. Honestly, I feel like it is too expensive, considering how there are better spec laptops available.
not really, T490 are basically the same hardware with a modest CPU refresh, otherwise almost everything is interchangeable (also with earlier T470 models). similar with T14 Gen1.
what’s troublesome are the S-suffix models and the Carbons and similar, they are slimmer and have one or both memory banks soldered and are single battery models. you can stll swap SSD, batteries, etc. and the serviceability is somewhat OK (way better than the mentioned e-waste but worse than non-S models).
