I really do need to give it more of a chance. I'm know my dissatisfaction comes from a place of ignorance.The GG gets a bad rap because so few people explore its library. And it had a bunch of great games that weren't on SMS (although even the SMS ports had value if you didn't have PAL game access). The GG Shinobi games are awesome action-platformers, better than anything similar on GB or Lynx. Devilish is a great ball/paddle game. Fatal Fury Special was as good as portable fighting got pre-NGPC. The Aleste games are among the best portable shooters. Crystal Warriors was an impressive SRPG at a time when so few got localized. I had both the GB and GG and I think they were a good match with different strengths and weaknesses.
Hate to post this, but the PS Vita. Love the idea, and some of the games were good, but the memory cards were an expensive pain (my 64gb had stability issues) and I felt the buttons/joysticks were too small, cramped my hands if I played for more than 10 minutes. I think I spent 3-400 dollars total on the device/cards/accessories and put maybe 25-30 hours total playtime into it over the ~4 years I've owned it. Feels bad :-( On the plus-side, this revealed what I've always suspected about myself but did not discover until I got my Vita, which was my first handheld: although I like the idea of handheld gaming devices, they really aren't for me.
Support was there early on, you should have jumped on so we could have got a few more first party games. Also indie and Japanese support was there for a very long time. You should check out the library some time.
I bought the special edition Spider-Man PS4 Pro because I was getting sick of my then-current Pro's fan problems.
Then I found out that everyone has fan problems.
The Spidey Pro was somehow worse, if anything, also.
Also this.Nintendo Switch. Barely use the thing and my joycon are drifting like there's no tomorrow.
