>what surprise me is that a Windows 11 Pro licence cost 259 Euro. Micro$oft still make a lot of money with windonws =)
Not really. Windows 11 Pro retail is $199 today which might sound steep but in comparison Windows XP Pro retail was $299 in 2001 which adjusted for inflation would be $500 today. Ouch!
Windows 95 retailed at a whopping $205 in '95 or ~$400 in today's money, while a retail Win 11 Home is $139 now.
So Windows has actually gotten massively cheaper, which is weird considering that OS complexity, update frequency has increased and SW dev salaries and expenses have gone up since then.
