iPod Touch concerns

My pre-order has yet to ship and I have a few concerns with Touch.

1) Lack of Mail application (gmail on the web may work instead)
2) No Google Maps application (google maps on the web may work, but goofy in comparison)
3) Inability to add Calendar events (seems like such an odd thing to not include)

My hope is that Apple will add these in future updates to the firmware.

I’d like to know the reasons for these decisions, but I’ll never know.
