I have already listed my problems. I have talked about them in great detail.
Yes. And you have unfortunately also talked about how great 98SE was which gives me a nice idea about your level of proficiency (or extreme lack thereof to be precise) so if your Vista probs are really irresolvable is most questionable.
Seriously, only a complete uber n00b would claim that 98SE was great. For starters you couldn't just let 98SE run 24/7. You had to reboot the system frequently to fix the issues that would begin to show up after a while of use (apps crashing inexplicably, short freezes, blue screens etc). The more load you put on the system the more likely it became that you needed to reboot. You couldn't just open 10 instances of IE or Netscape for example. At least not for long. The system got clogged up quickly when you did a lot of things in parallel or simultaneously. Windows 98SE (like all previous incarnations of Windows with 16-bit leftovers) just wasn't made for real multitasking. That's also why you had to reinstall 98SE every few months because the system was very prone to getting clogged up and accumulated all sorts of junk over time that would lead to random issues from crashing to freezing to obscure error messages and so on.
Please. Get real and refresh your memory. 98SE was OK for its time but I'm sure glad that frequent reboots, blue screens and reinstalls have become a thing of the past thanks to XP. Honestly, 98SE sucks giant loads of ass compared to XP.
