A bit of a swing and a miss on either S7 configuration. One the one hand you get an Intel/Nvidia powered option that sucks the battery down in unreasonable time while on the other is an amazing AMD powered option that has the 2nd m.2 slot removed.

In either case the memory options are sufficient for gaming, but perhaps not so much for who this particular article was directed at.

If either mod can take a 32GB module for a total of 40GB as youtube reviewers are stating, that's probably a reasonable tradeoff. If not, 24GB is the maximum.

Being DDR5, the dual channel argument above is out the window as matching sticks sized sticks are not required. Individual DDR5 modules themselves are dual channel...

Anyway, I ordered the S7 AMD Advantage copy of this with extremely high reservations given the single drive limitation. I'm now forced to buy an 8GB SSD, which is ridiculous given the amount of real-estate left in that chassis.

Why...

All Legions are that way which is good, don't know why Slim is singled with subpar cooling that the others don't have.

Slim series is completely useless for efficient work and business. It always has ridiculous 8GB of memory soldered + one slot, which limits the speed dual channel mode to only poor and funny 16GB. For work, this is just a ridiculous amount of memory in 2022 and even more so in 2023. Minimum -is 32.

Moreover, this series is too noisy in office workload even in balanced mode. What few people like, sitting at home in a quiet environment.

Otherwise, it loses for Legion 7 2022 on AMD in everything. A simple question - why does anyone need this series in practice? Except perhaps a sharply lower price in the region of $900-1000?
But this (price) is not so, right?

Offices buy just L5Pro on AMD and would buy L7 another 10 times more if Lenovo didn't do something stupid - they wouldn't sell L7 only with powerful discrete chips. It was enough to make a model with 3050 and sales, with a sharply lower price due to this, but the starting 32GB/2TB from factory in the this configuration is around $1100-1200 and sales of such models to businesses would increase significantly. Offices and work do not need expensive discrete gaming chips.

I personally do not need a discrete (at best 3 (4) 050), the silence of the processor at medium loads is much more important to me. And a lot of memory, the more the better, expandable. And it is important to have at least 2 M.2 slots (and preferably 3). And I don't need parrot case lighting - instead, solder a couple more heatpipes and increase the weight of the radiators and the size of the coolers to further reduce the noise on AMD versions with R7.

In fact, the L7 c 3050 is killing sales of Lenovo's T/P/W series on the net, except when people really need a solid solution for traveling and work in "fields", where the "gaming" series loses in real strength to the expensive business series. But for most, a really reinforced motherboard with a magnesium chassis and a very durable case are simply not needed. Most of the time, such laptops are at the workplace in the office or at home, occasionally being transferred from table to table and from building to building, and at home also on the sofa couch to surf the Internet comfortably reclining or doing something not very heavy.

When manufacturing companies realize that the economy has become remote and people just need convenience, comfort in terms of a variety of ports and their convenient location (and for right-handed people, of whom the majority are also for the few left-handed people)
and the most important thing:
1. optimally tuned for quiet operation up to a level of 35-40% in terms of core load, with the best screen possible for vision (and this is only 4k@120Hz+ for today with contrast from 1500:1), then sales will immediately go up.
2. A comfortable full-fledged keyboard that is as close as possible tactilely and, if possible, fast  blind typing without fruitless attempts to retrain with a high-quality full-fledged desktop one, then sales will start again. And laptops will be bought by hundreds of millions, preferring desktop self-assemblies.
