I'd like to use a PPC wirelessly in my house, but i can't decide between a CF 802.11b card and just getting an e740. I generally use my PPC (an E-125) for games, music, movies, and internet. I've been hearing that external CF cards get better reception, but use more power. As for a WAP, I'm going to get a Linksys BEFW11S4... If i get a wireless CF, which one should i get? Ive looked at the Linksys WCF11/WCF12, the buffalo airstation (WLI-CF-S11G), and the symbol/socket cards, which are the same. Any suggestions?
