Okie doke - so questions!

1) Will our characters know the cash prize involved?
2) Is the PDA somewhat designed like a tablet or...? (It sounds like a stupid question, but better safe than sorry ^^;) And if so, I assume that there will be little apps/tabs/whatever to tap to pull up the map, PDA designation, "mission," etc.?
3) How big are these PDAs? Ipad size? Smart phone size?
4) Will these PDAs announce to everyone that an objective has been met? (Say my character had to kill x amount of people. Upon killing someone, will it announce: "Three to go!" or will it be much more subtle than that, say through a head implant, headphones, text only?)

I have a few more, but I'll start there. ^^;
