Would like some info on the differences between the LG Gram 17 2022 and the 2021. On Amazon are the only 2022 ones labeled '2022' or are some of the others this year as well (and if so, whats the easiest way to tell)? Is there much of a difference between the 2 years models other than the CPU, and is that alone a big enough difference to justify getting this year over last? Does the WQXGA screen justify a higher price (meaning, is it that much better?)
