I went from a cheap mp3 player that I could just plug in to my computer and drag in music to an iPod which forced me to download the iTunes bloatware create an account and then took 100x longer to transfer music because of the pointless conversion each file had to undergo. This was my first and last experience with a personal Apple device. Ended up putting some old pop music onto it and giving it to my grandmother after 2 days. Uninstalled iTunes and went back to using my cheap mp3 player until I replaced it with a smartphone.
Coming in as a close second place, an all-in-one Sony Vaoi computer that cost a fortune and had shit performance. Took daily nags to Sony before they took it back and gave me a refund. I find that Sony's hit and miss though. My favourite smartphone (Xperia Play) was Sony, and I love my Sony Bluetooth earbuds. The Sony Smartwatch was shit.
Honestly, this is pretty impressive IMO. Particularly since visa-free travel is not reciprocal. The below is just plain wrong; Australia is even less open than it appears:
Barring some niche cases (e.g. royal family, military/crew, transiting, Torres Strait Islanders), only one country's citizens can travel to Australia without prior visa authorisation; New Zealand (and even they can be refused clearance at the border). Every other foreign country needs to apply for and be granted a visa before they are permitted to board the plane. Australia has somehow managed to convince 33 countries that their ETAs and eVisitor visas are not really visas. They just happen to be permission that a person needs to obtain before they are allowed to enter a country... If only we had a word for that.
I'm honestly surprised how well the Australian passport performs considering Australia effectively has a universal visa requirement. That being said, it's also one of the most expensive passports in the world.
