regarding gaming laptops, I had one until a couple of years ago, which cost me 1400€ -sigh-.I would hold off on buying a Steamdeck type thing at this time, I have a feeling competition will be thriving soon. Also at those prices a gaming laptop makes a lot more sense to me.
The differences with a device like Steam Deck are huge:
- more powerful
- heavy no matter why they say
- not as mobile
- no integrated gaming controls
- Heat is a huge problem, not even a cooling base is going to change that
- On battery games drain the energy in a jiffy
- If you want the most performance (which you usually will 'cos of the screen native resolution) you MUST connect it to the wall
- if you do that though, and after using it for many hours, the battery suffers in the long run, shortening the battery life
In my case the laptop's battery got to a point where it became useless. It said 80% charged then all of a sudden, bam, the computer was shut off and nothing could be done, the OS had no time to go into hibernate mode.
Finally it got to a point where it was as if the battery didnt exist. If you unplugged the laptop, the computer turned off like a desktop PC.
I could reuse some of the components on other computers though, or the HD as a external drive for my desktop PC and so on.
