Wow... nice post, BunBun...
I must say that I agree with most of your "complaints", Windows 7 is just different... The way it manages open windows, how it manage open tasks, how the new superbar works. I've been through all of those, and after everything comes down on me, all I can say is that "Windows 7 is different". I have to "adjust" to use 7, there is no other way. The way Microsoft breaks "how things are done in XP/Vista" (that include taskbar, notification area, the "Move" command [I too was looking for that, found it in Task Manager]), I applaud them for that. Microsoft should have rebuilt taskbar long time ago. I had my own headache with taskbar area, most of the time I'd have a scrollbar on a double height taskbar on a dual 24" (spanned) display, that is 3840x1200px...
Here's what I think is better in 7:
1. IMHO SuperBar is a little better (not perfect) than the original taskbar, it can hold quite a lot before I got the up/down scrollbar on the taskbar. It groups each "task" to it's icon, and show it visually using Aero peek (though sometime the mini preview window went MIA for some unknown reason, no biggie). I need several days before I can optimally use it.
2. The new "notification pop-up" you argue for few pages (although in the end you said it's quite a bit better than the old one) is one of the feature I like. It does take me several days to adjust, usually it will expand to the left, slides open, now it pops up... no biggie, I can see/select much better, I just need to watch more carefully because it's arranged as a "grid".
3. The overall system performance is one of the feature I really like. If you read my system specs, my computer is inferior than yours. But for now, this workstation can do what I want to do up to "good enough" stage. When I use XP, it is true when first boot up, XP is plenty fast, memory usage very very low. But over time (my XP's uptime is above 1 month normally) it slows down. Not in snail slow, just slower. Many apps would start to behave weirdly (maybe then memory manager went south?). Windows 7 is somewhat more resilient then XP in that aspect (I totally skip Vista, so I don't really have anything to say about it).
I must say, I do feel "limited" when I use 7 for the first time... UAC notification takes time to show up, changing ANY settings that have shield icon next to it's text will take sometime before it responds, installing programs will invoke UAC warning, and so on... These small insignificant annoyance can build up and make a "Power User" blow up. But all in all, it's much much better of using my hardware to the limit than Windows XP. Now, running 2 virtual machines doesn't bring the whole system down to a crawl...

And about Pagefile, if you completely disable Pagefile, maybe performance wise you might not feel anything, but when Windows crashed (BSOD), you won't be able to collect the dump if you completely disable pagefile. I personally set my pagefile to 1GB (of 4GB physical memory) just for the memory dump feature. So that I'd know what crashed in event of BSOD.
After reading several post in the first page, I can't hold the urge... For the record, eSATA is just as fast as internal SATA, there is no difference at all, I'm on schedule to move my Windows volume over to my homemade SAN. The SAN volume is faster on small file operations (RAID6). If I can save some more money, I'd change the SAN <--> PC interface to FC, that'll give me ~400MB/s to play with, a nice trade between volume expandability/speed...
Enterprise class hardware, the one that uses tens of gigabits of bandwidth in storage traffic uses external storage, ALL of them... If you want to boost your storage speed through the roof, the only way would be to move your storage to external device, it's a lot more manageable than internal storage and much more expandable.
