LG's G-Slate or Asus Transformer

[Stabulous]

Hello All,
I picked up a G-Slate through T-Mobile with data plan for $500.00, let me know what you think is the better buy between the 2 tablets would be. From what i've learned from the G-Slate and what i've read about the Transformer I will list out what I've come across so far. (Correct me if i'm wrong)

LG G-Slate

1. Dont care about 3D.
2. No full size usb port.
3. Sound quality is eh.
4. No expandable SD slot.
5. Battery life 8 hours?
6. Nice looking?
7. Response time is decent, i'm sure they are pretty much the same.

Asus Transformer

1. WiFi only
2. No full size USB (Must purchase dockstation, which includes 2 USB ports.)
3. SD slot included.
4. Battery life 8 hours? (Battery life doubles with dockstation)
5. Not sure about sound quality.
6. Gorilla glass for the touchscreen (not sure what that is, but ok) *lol*

I know i'm missing some more key features, I am thinking about returning the G-Slate and picking up the Transformer. I really would like the expandable SD slot and full size USB port.. Input and feedback is greatly appreciated!
