The "other" primary change is that if you pay for additional storage, you loose your free storage for mail and photos; all storage needs are taken from your G1 paid space. I suddenly found that Google had moved my mail and photos into my "new" G1, reducing the amount of space I had available. Prior to "new" G1, I paid for EXTRA 100gb and that was ADDED to my account allotment, for 145gb total. Now I have 100gb total.
No longer a deal, the price just jumped up 45%.
