Asus MyPal A620BT vs. A716

I was interested in getting one of these after reading several reviews off the net. I plan on using it to jot down notes on the worksite, surf the web, watch movies, and play video games. I'm having a problem picking one of them thou. The A620 is slimmer and a bit more compact than the A716 but doesn't have the WiFi built in. Are there any more advantages/disadvantages to gettin either of em?
