Question for PSP/PS3 owners

[NJMetsFan]

I have a few questions to you guys that have a PSP and a PS3. I'm going to Iraq for 6 months and I currently own a PS3. So, I think a PSP will be a pretty good idea to keep me occupied while I'm out there. I also want to use it to talk to my wife and kids while I am gone.

Before I make a purchase I have a few questions I would like to get answered. I know with the current PSP I can use Skype. But is that the only way I can use the PSP to talk to my family? I would like to know if I could chat or video chat using both systems through the PSN as well?

I leave in August and the Go won't be released yet, so that is not an option. I am thinking about buying the PSP-3000 then buying a PSP GO and selling the PSP-3000. Other than better portability, bluetooth, and no UMD, is there another reason to get the PSP GO? Do you guys think that is worth the hassle or just keep the PSP-3000?

Thanks for any help in advance.
