I never minded the removable dew shield, putting it on and taking it off just became part of the setup process, which on my alt az mount took all of 7 or 8 minutes.
Sliding dew shields are just so much handier and you don't have to find a place to store the darn thing if you take it off.

Is it still made? Who sells it?

I'm sure if the scope had a sliding dew shield I could find the same reasons why it was more convenient than a slider.
But another 20 seconds isn't going to make that much of a difference. But messing with a CF d.s. in the dark, in the winter, etc, could have consequences if fumbled or mis handled. As you can see, it can go both ways.

Very nice! Its own leather case. But why don't you store it on the scope in the ES case? Faster?

Perhaps it’s the way I use the scope: mostly set up on my lawn for 3 to 5 days/nights at a time, or in the field as a second scope along with my 20-inch Dob. I have a pickup truck and a 5x8 foot cargo trailer, so I have plenty of space to spread extra stuff out. I also care little what a telescope looks like. My interest is far more in what it shows.
I have had to put glow-tape on the case to keep from falling over it in the dark at places like Cherry Springs, where it blends in with the grass. Why do they make cases black?

They are replacing the old aluminum one with a carbon fiber one. It is due for release in March.
I hope march. I emailed them and they didnt have a release date. My mount is here just waiting to buy the scope

I've had a 4" ED102 for a couple of years, and I'm sad to hear they're changing the shield. The rigid/removable design works better with cable management IMO, and even serves as a stand when working on it. Plus there's the option of switching it with something aftermarket or of your own construction. The scope is so nice I'm almost afraid to use it, now it's going to be irreplaceable. I guess they're just listening to their customers, but I hope we as customers aren't succumbing to conformity.
You bring up some good points. I feel the same about the dew shield on my new ES ED152mmCF. At first I through, 'gee whiz, for a 6K scope, they can't put a retractable dew shield on it?", but then I pulled it out of the case, and put it on the already front end heavy OTA. I weighs 2 lbs, 6 ounces. Mine is felt lined. It could be a help for dew heatters, and others home made dew shields like you say, if you would decide not to use it /put it on. And I weighed the whole OTA with finder, DS, diagonal, and a 1 lb EP, and rings, and it was just at 30 lbs. So not using a 2 lb dew shield 'could' make a difference on a 30 lb max mount like a Atlas who's 'capacity' is 30 lbs. (it still doesn't take into affect stability in wind, etc). And you'll never scratch the CF moving it up and down. But it is a pain to pack onto the OTA for storage. I might just leave it out and transport separately, or use my 'foamie' dew shield made/bought at JoAnne's.
On the other hand, it sure would be nice just to push it down. No chance to fumble or drop or scrape.
I think we all succumb to marketing and other's ideas some time, but in this, I'm happy to have the one that comes off for its ability to let me decide 'on or off'.

Up on Mt Lemmon we use a TeleVue 127NP as a finder/wide field scope on the 32" RCOS. Gravity slowly but surely pulls the retractable dew shield down over the course of a night - something that would be quite annoying to me if it were my telescope. That slowly sliding dew shield would be enough to throw off the balance quite a bit if it were on a typical amateur mount.
