Bought the Dell Precision you linked to. I phoned in to ask a few questions, and the sales guy told me it was the last one (suuuuure). He asked if I wanted to put it in my cart so I agreed. After purchase, I went back to check this and sure enough, it says "currently out of stock". Maybe I did call just in time. In any case, he also gave me a 50$ discount on top of it with free 3-5 day shipping. So, overall a very good deal, especially compared to what that amount would buy in a new device.
I am now looking at that 27" 4K monitor and some type of wireless keyboard and mouse--not terribly mustacian of me as my old monitor and keyboard/mouse combo still work (With a few minor issues). However these items will certainly be a nice upgrade and worth the money considering I spend several hours a day at this machine.
The Dell Ultrasharp monitors look good and seem to get very good reviews--not sure you're going to notice 4K on a 27" monitor, but nevertheless, still a nice upgrade over what I have now. I used to have a 30" at work, but found it a bit tooo large.
As for keyboard/mouse combo, it MUST be wireless. I like some of the backlit/gaming ones I see, but these all seem to be wired and/or needing to be recharged. I also like a lot of hard buttons--I have a button to summon the calculator as well as volume, mute, track advance, play pause, etc on my current one, and would like those and more on a new one. I also like the keyboard and mouse to be as quiet as possible.
As for Sasquatch, I have been fascinated with this since I was a little kid. When I was in second grade, I borrowed a book from the library called
Nobody Meets Bigfoot (should track down a copy). No, I don't believe they exist, nor do I discount it entirely. (I do have a Ph.D. in bio BTW FWIW) However, I would highly recommend this book by John Zada--
In The Valleys Of THe Noble Beyond. Author takes a very dispassionate approach, interviewing many native people in coastal British Columbia, sasquatch researchers, etc. His descriptions of the terrain, people, culture, history, and natural history of the area make the book worth reading even if you think Sasquatch is total BS. Perhaps you would enjoy!
