Can you elaborate on what you think will happen? It seems difficult to screw up the idea of "selling small computers".
Prices will go up. They will split out basic features into 'premium' models. They will no longer sell cheaper models entirely. They will find some way to shoehorn a subscription service since that's what every investor wants now. RPI Os will be littered with 'partnerships' and they'll find a way to make it difficult or unpleasant to use anything else to avoid them. They'll rush to do yearly releases instead of focusing on quality and support. I wouldn't be surprised if they break their guarantee to keep manufacturing products until a certain date.
But hey, maybe a sudden cash injection post-IPO will help them actually sell their products.
Of course, then they’ll have the problem of raising their prices, and people will eventually say, you know what, no thanks, and just use a competitor SBC.
You already basically can’t buy from them at a price that makes sense, or at all.
And the really cool thing is their website lists a bunch of legacy products that no partner sells anymore so you get the great experience of trying to figure out what the hell you can buy from them in the first place.
It's been easy to find a Pi in stock for months now. https://rpilocator.com
Maybe they'll even drop R&D and just sell rebranded Chinese boards as RPi.
