So which CPU will you choose: Intel Core i3 1115G4 or i3 1215U?

I did almost end up with a system with a Core i3-1115G4 in it but get the better upgrade in Core i3-1215U. Still shocked that i end up with one of the latest CPUs to come out this year when i didn't expect a laptop with a 12th Gen CPU to come out as yet.

Which laptop did you finally end up buying? I am also considering buying an i3-1215U powered laptop but am unable to find any optimal option.

Vivek, The Lenovo IdeaPad 3i is a solid option. I've had it for over a month now, and it's delivering great performance, especially with an additional 8GB RAM stick.

obito, Hey, I’m planning to buy the Lenovo IdeaPad 3i too with the same processor, how fast is your CPU? Is the ram easily upgradeable? How’s the screen brightness? It’s like 250 nits right?

New, I previously owned a laptop with an i5 10300H, and despite its lower power consumption, the 1215U feels smoother - it's an amazing choice for everyday laptops as it handles almost everything quite nicely. I currently own a Lenovo IdeaPad 3i, which comes with an IPS display, offering 250 nits of brightness, excellent viewing angles, and high contrast - I would definitely recommend going for the IPS version. It also comes with two RAM slots for future upgrades. Right from the start, I installed an additional 8GB stick, which is something I would recommend you consider doing as well.
