I see that PM found the sweetspot for middle data users. But, there are many others who just need enough data for some occasion like transiting or going on a local trip. It even comes in handy when there is a problem with Wi-Fi. I am sure having as little as 1GB was the option that suited many. I see that PM is targeting user for that awesome $120 plan, but it will not be the choice for many other who don't need that 6GB or 3GB data. I don't see this hurting when you will be targeting light and medium data users. For light data users, they got no choice. There is a big difference between 1GB @ $90 and 3GB @ $111. I do not see the point to just ignore light data users. That 3GB options should not be offered because there is only $9 difference to get extra 3GB so who wouldn't?
So, i think PM should bring back that $90 / 1GB plan because getting on the plan without data and than adding $30 add-on would be too much.
