Note I was doing this earlier but my computer decided to freeze)
So some people got the Steam Deck, Valves prized child for their gamble in the console race early. It will officially release February 25th, 2022. Now I don't think I have seen a SINGLE piece of negative feedback on the Steam Deck, but doing my research, here is WHY you shouldn't get it
Battery Life
It's ABYSMIAL. It only lasts for 2-5 hours when playing. Heck, the original Switch had better battery life (2.5-6.5 hours) and the newer versions are SO beating it in the life department. Battery life has proven keen that it matters. The only handheld Sega did sold 11m in 7 years from 1990 to 1997 sold poorly partly do to the fact that it took SIX DOUBLE A BATTERIES because it offered color and only lasted for 4 hours, when the Gameboy took 4 and lasted 10. If you use your computer for Steam, you can play for as long as you please since it doesn't use charge
Games
Well for starters, it won't have every Steam Game. Now that wouldn't be a problem, if it's game weren't ALREADY ON CONSOLES FOR AWHILE NOW. Games like Cuphead, Dead by Daylight, FNAF Security Breach, NBA/FIFA, Doom, Fallout and more have already been on consoles, and this makes not having every steam game worse, because it means it might not have many exclusives, which can make or break a consoles chance of succeeding.
Nintendo
Yeah I don't think I have much to say. Switch is out and has the portable market secured, and with the Switch out and still kicking, it will have some heavy competition. And with a chip shortage, it will be hit harder than it could be if Nintendo's grip on handhelds wasn't a problem.
Price
So if you want a Steam Deck, you will fork over 400 dollars for the base model. There are two other more EXPENSIVE models, but just wait a bit for my comment on that. I don't think any portable has been that expensive, and again, poor battery life will suck. You can buy the Switch OLED Model for 350$ (not including Metroid Dread) for a 7 inch screen, amazing colors and 64 gigabytes. Speaking of gigabytes
