As for hard sided bottles, modern sport caps from Klean Kanteen have a pretty high flow rate due to an extra valve and I can easily reach it while riding and drink from it. The bigger bottle is mostly for storing extra cold/hot water for either refills or for making tea.
Hydro Flask has a sports cap with better insulation but I don't like the way the valve works.

I'm not from the USA so ice machines are really uncommon in most of Europe. Sure I'll have a small amount of ice made at home but most of the time I just put a small amount of cubes in there and top it off with cold water.

I never really saw the appeal of plastic bottles. Sure you can squeeze them for quicker drinking but I associate then with cheap smelly plastic and getting really dirty very quickly. Then again I come from the hiking world. I don't know any better than Nalgene style bottles, stainless steel flasks, Platypus soft bottles and Camelbak hydration systems. They all have their place but I prefer the neutral taste of bottles over things with a tube.
