Photo editing is my last holdout. And a European-compatible banking software.
Everything else works well on Linux. Gaming included. I've run Linux many years, in fact.
But Capture One and Lightroom are not available over there, which is what draws me back to MacOS. Of course I could just use darktable. Have done that for several years. But at the end of the day, I just prefer Capture One, and that's enough reason for me to switch my OS.
Some european banks are still struggling with the whole internet concept and have win32 apps using emulated dial up for both home and business customers.
The few I had a pleasure of using have a really good browser and mobile app support. The only problem I ran into is that sometimes mobile apps refuse to run on rooted Android devices.
Raiffeisen in Austria is/was? one of the stragglers, but I haven't dealt with them in 2 years or so - a company I worked for was stuck with it, but I noped out for Erste Sparkasse ASAP, and they let you do everything in browser. (Since 2011 at least.)
Raiffeisen in Russia let one do everything in a browser on Linux since 2008 for personal accounts. Possibly earlier, I did not have an account with them back then. For business accounts, it's since February 2016.
A good, HBCI capable software that can list transactions and make transfers from and to multiple banks. Think Quicken or MoneyMoney.
The browser will only ever log in to one bank per tab, and with different UI per bank. If you have more than one bank, it becomes a hassle quite quickly.
