Hah well most everything is made in China

I'd be wildly surprised if the Pioneer was fully made in the US. The difference there is that the Pioneers are built like absolute tanks.
The vinyl versus digital argument for DJing, while a bit different than it is for just listening to records (I'm in the vinyl is better camp there too), there's some similarities. For me, it's not quite as much about the audience. As a member of an audience, I'm far more impressed if I see a DJ bust out a real (not timecoded) record. But, you're ultimately right, usually it's about the music and party and not about what the DJ uses.
Having said that, one big plus for vinyl, and to a lesser extend things like CDJs - what happens when your hard-drive crashes, you drop your laptop, spill something on it, etc.? Did you bring two computers with one already setup and ready to go? Few people do that, but if you're using TTs or CDJs and the like, you can keep on going.
For me, the tactile feedback and sound of vinyl does it for me. Even when it comes from a digital source, the sound of vinyl I find more pleasing and it's fun to see how components influence the sound. Digital is a cold bitch, frankly. If you don't warm her up, she's going to stay cold. And even when you do warm her up, don't expect anything kinky. That's why good mastering shops run digital through an analog process (even tape) and back in. And it's why, I think, the sound of modular synthesizers pleases me more than, say, my Virus and certainly soft-synths.
The tactile feedback of vinyl is huge. Using auto-sync is largely thought of as a crutch by many DJs and after doing without for some time, I tend to agree. You can be MUCH more flexible and creative when you're the one that has to think of beats. Consider how to sync something in 3/4 with 4/4 and the BPMs to do so all with sync.
You don't need a turntable to beat match, but as you pointed out, jogwheels suck. At least mine do unless I'm searching through a track or using them as a big effect knobs. And, either way, I just don't feel as intimately tied to the music.
That's why I'm going to do both. Best of both worlds. If I want to cut up a track to bits, I can easily do that. Though modern mixers and CDJs and things can do similar things, I do find that such things are certainly easier with software. My favorite tracks I have and will continue to try and collect on vinyl and spin those unless I want to do crazy things with them. And perhaps after that I'll move to CDJs if the hobby takes off in more places than my bedroom and an occasional small show when we're doing a party at work.
All that said (and it was a lot, sorry - I'm bored as my main Internet connection is down and am on my slow tethered cell connection ;) ), DJing is a diverse art so ultimately whatever you use is up to you and that's the way it should be. I find DJs online (such as places like /r/djs) have way to much hubris about the whole thing. Use whatever makes you, and your audience happy. Just keep pushing the envelope.
