Anyway, if you don't want to read a HUGE article (it's REALLY long), here's the TL;DR (that's "executive summary" for you business students) version:
- It's Vista
- It's better than Vista
- XP is still somewhat better than 7 (not by much, though)
- Resource management in 7 is better than Vista
- If you don't like Vista, you should upgrade (this includes to XP--yes, that's an upgrade)
- If you don't like XP, you should skip Vista
- If you like XP, you should stay where you are
All in all, it's been pretty stable. Oddly, it's more stable than XP. I used to crash explorer--incidentally, this is the same process that manages the taskbar--at least once or twice during a typical day. I've never had one such crash in 7. There are some problems; as Turus pointed out in the comments on my blog post, power management is a bit too draconian by default, and you really need to tone down the settings unless you have a strong appreciation for replacing hard disks every 3 months.
So, read it and tell me what you think. If it's too long, don't bother. Trust me. I do have a lot of shiny pictures, though...
