Does anyone have feedback on the Wifi-Korea ESP vs Olleh Egg? The ESP seems like a really good deal - I'm just wondering how it'll work in conjunction with Google Voice/Hangouts now that I have the Ipod Touch in hand. Tested it this past weekend and it's not the greatest with my Freedompop Photon but that's probably cause the FP Wimax coverage and performance is so terrible in general.

It sounds like ESP would give a constant connection and might work really well for VOIP calls. Cheaper than the Egg too.

It would be great if anyone has used either or (or both) and can comment back with more details or reviews.
