First let me say that I love my steam deck and I actually love to play this thing... in my bed with the charger connected.
People keep saying the switch is underpowered (that's not the problem, the problem is the Switch is underclocked) and after the steam deck I'm actually more impressed with the switch/lite than I was before, because for the size/performance/cost/games is actually a fantastic portable machine.
If you just want a handheld gaming PC the steam deck is exactly that, so why this thread? I'm going to judge it as a portable device.
If the switch is underpowered, the deck is oversized and the fan is an actual vacuum cleaner, this thing is so loud that I thought it was defective at first, no wonder why Nintendo didn't make a more powerful console and underclocked the thing.
Now let's talk about the battery, with the kind of games the steam deck plays, you will get 1.5 hours at most so you will have to buy a battery bank or just play connected to the charger to not deal with low percentage of battery for longer gaming times.
Now let's talk about game optimization, if I want to play GTA V I gotta download the whole 107 gb, even if I play at the native resolution since this is a PC I gotta download the whole thing. An hypothetical GTA V on the switch wouldn't not need that because it would be optimized for the console and they wouldn't not need to add all the 4K textures, bells and whistles. So yeah the deck has more storage and you're a going to use it. There are a few more things but I think my point is clear.
I'm still impressed with the deck and the hardware is fantastic, but I'm not going to act like this is not a test/beta product for the better things in the future.
Probably one of the worst opinions I've seen in a while.
