Hello
I have been interested in both of these products as well. I do want to mention that there is an adaptor you can buy so that the SD can be used wtih a CF. I ran into it looking at different pda accessory websites. So for that reason that problem solved.
I have seen the 330 at BestBuy, I am a rep for a wireless company so I do some sellig there. It is nice looking, I am waiting to play wiht it a bit and to read the manual through as I always do
The viewsonic I am really wanting to see it and know if it lives up to the hype. I admit it has my interests perked
