The basic differences between the Gen 3 Standard dish and the new Mini dish:
Price of hardware:
The Mini is $600. Gen 3 (as Bob stated) $300
As with all things Starlink, time will tell if prices drop. They usually do...
Plans and pricing:
As I understand it, the Mobile Regional and Mini Roam plans are both available for EITHER Gen 3 or Mini hardware. I cannot find any verbiage stating that the plans are specific to hardware. I think the Mini Roam started as a "mobile plan" to fit in with the mobility of the Mini, and using "Mini" in the plan name has created confusion.
Either plan can be paused. I am starting with the 50 Gig $50 plan. Additional Gigs are $1.
Here's my logic: I am essentially paying $1 per Gig. I have estimated our streaming habits "on the road" to be within 50 Gig. Even if I double that usage, I would be paying $100 total... still $50 less than the Unlimited plan. If my calculations are WAY off, I could simply switch to the Unlimited $150 plan for the next billing cycle.
Mini has integrated router... all other dishes the router is separate:
The Mini dish has the router integrated into the dish itself... the approximately 50' cord carries power only (30 volts) to power the dish. The router inside the dish broadcasts data via Wi-Fi... no router inside the RV needed. However, there is a CAT6 port on the dish, so (using an appropriate length CAT6 cable) you have the option of using the dish "hardwired" to a router inside the RV. From inside the RV, I have not noticed any degradation of the signal from the dish itself - with the power cable fully extended.
Size and weight:
The Mini is not much larger than a tablet computer with similar weight. It is designed to be portable to fit in a backpack and powered from a portable battery if desired.
Performance and power usage:
The Gen 3 is capable of higher data speeds. In tests with the Mini, I've found speeds very similar to what I get with our home based Spectrum cable (typical 122 down, 12 up). This is fine for us on the road... we can easily stream video with that speed... more would be a waste. Someone working on the road might want more, it's dependent on YOUR use case.
There's a penalty for the extra speed though - The Mini uses about half the power (I've confirmed 20 - 40 watts) of the Gen 3... which may or may not be an issue depending on shore power, etc.
"In Motion" use:
There are YouTube videos of tests using the Mini in a fixed mounted position on a van roof... WHILE IN MOTION at 45 - 50mph. The tester DID NOT have the upgraded "in motion" plan; just the basic "Mini Roam" plan ($50). Other than basic obstacles interfering as with ALL Starlink dishes, it worked great.
We will be taking the Mini setup to the mountains in West Virginia in a couple weeks for a 3 to 4 week trial. The brother-in-law will accompany us with his motorhome. He has a new Gen 3 setup. I will post results occasionally along the way.
