Yes these new plans are a big let down, and step backwards in my opinion (removing rollover data) for myself and others.
But I guess Skinny are targeting the users who don't care about rollover, or speed limits?

In our household we have multiple Skinny users, and like others have mentioned earlier, we change between plans to get more data depending on our needs.
e.g. One month of $66 plan (30gb data), then a few months of $16 (1.25gb data).

Just look at the numbers:

Previous year with Skinny (13 periods in 1 year, 28 day billing)

• 2 x $66 plan + 11 x $16 plan
• Year Cost = $308 (avg $23.69 / period)
• Total Data = 73.75 GB (avg 5.67 GB / period)

Now with the new Skinny plans, if I wanted to try and get close to the same amount of 'full speed' data:

• 13 x $36 plan
• Year Cost = $468
• Total Full Speed Data = 54 GB (4.5 GB / period - LESS than above)

Meaning instead of spending of $308 per year for 73.75 GB full speed rollover data, I'm spending $468 for only 54 GB full speed data (not rollover).

Based on 2degrees prepay, I can do this (12 periods, monthly billing)

• 3 x $70 plan + 9 x $10 plan
• Year Cost = $300
• Total Rollover Data = 77.2 GB

Our household is now looking at moving all SIM's to 2degrees - fingers crossed 2degrees don't introduce this silly 'endless data' and get rid of rollover data too.

One the reasons we prefer 'full speed' data, instead of this slow 'endless data', is we hotspot a lot, e.g phone to laptops, and work remotely, etc.
