Guess I'll answer my own question.
NASCAR shooting to implement fuel injection in 2011: By the time the 2011 racing season gets under way, the only place to find a carburetor in the Sprint Cup Series might be in NASCAR's Hall of Fame. Officials said today that they hope to replace carburetors with fuel injection, and have been testing potential systems with an eye toward making the change as soon as possible. "We are in the process of the development and the testing and have been for probably six or eight months," " said Robin Pemberton, vice president of competition for NASCAR. The easy part is to just build the fuel injection system. The thing that we need to put into play is how are we going to regulate it, and what's going to be fair for everybody?" NASCAR is one of the only racing organizations that continues to use carburetors in its series. Fuel injection is a more accurate, and efficient, way of delivering fuel into the engine. It has been around since the 1950s and has been in place on all passenger cars in the United States since the late 1980s. Pemberton said some Cup teams have already been developing and working with systems with the expectation that such a move would eventually be made. Some teams, Pemberton said, "do have track time … on their early production or early prototype fuel injection system. "So our goal is to shoot for 2011," he said. "I think that's pretty aggressive. "We are pushing hard."(SceneDaily)(1-23-2010)

I've been dealing with FI vs Carb since 1968 and the early Bosch J-Jetronic Systems on some German cars . . . once you get comfortable with FI and the electronics behind it you will NEVER EVER go back to a carburetor. Damn but I love my Delphi FI system! The ability to micromanage it with the TSS System . . . First Class Intelectual Chewing Gum for the Geek Motorcyle Gear Head for sure . . .

A buddy of mine switched his Street Glide over to a carb. It runs fine and sounds good. No one appears to mind while we wait for his bike to warm up. 
This is my first bike with EFI. It's worlds better than anything with a carb that I ever owned. My 2 cents...

Rode my 65 through that area. Carb is a stock Linkert. Not a problem. The run through Rocky Mountain National Park on same bike was a whole new experience. Couldn't do anything to improve performance. Think a motor with FI would have performed much better.

If my bike had a closed loop Delphi system on it, I would keep it. But it has a shitty open loop MM system. Even a Bendix carb would work better than that junk. I'm putting a CV on it as soon as I get the last few little parts in hand. And when riding season comes to a slow down in 2 months. June, July are a bit warm for riding around here.
32MPG and no power and a nasty cough for the first 5 miles aren't my cup of meat.

EFI engines start immediately in cold weather. They don't stumble and cough because the bi-metallic "automatic" choke sticks. They don't need 15 minutes to warm up before they run properly even in 50-degree weather.
In the modern world, the carburetor does have its place, but that place is on lawn mowers and chainsaws.

I don't.
I tend to hang on to my 'older bikes' and just put them in storage (semi-retirement mode) when I don't ride one all that often.
In fact I own 7 of them right now..
When it comes to making modifications to any of my bikes considering if it mighyt have a negative impact to the "resale value" is the last thing I would worry about.

I didnt by my bike as an investment, I bought it because I enjoy it, working on it, riding it, the quality time it gives me with my dad and my daughter. On a bike that I am constantly changing, Carb makes more sense to me as I can easily rejet after doing pipes/cam/P&P for less then 10 bucks in parts. EFI is a whole different beast, and our delfi units are no where as *open source* as their automotive counterparts. I was running a fully custom tune on my Civic with $30.00 in parts, and free software online. Our bikes are not as easy as plugging the ECU into your laptop with a harness and adjusting whatever you want. And since I have no factory or extended warranty on my bike, I really like the ability to work on it myself if something happens on a road trip.
there is a lot to be said for being able to being able to make quick adjustments. My bike has aslo been over the top of the mountain from Yosemite, over to reno/tahoe area, and I didnt loose as much power as the Fuel injected bikes I was running with. And, I had the ability to make adjustments, where they did not (however I didnt have to). Its not that hard to carry a screw driver with ya.
