What's the difference and do I need one to use the other? I wanna dump this wireless router (Belkin) cause it sucks ass in both setup/tweaking and connectivity. I'm looking to get an Airport basestation off eBay since I've converted 2 people in the house to go Mac and this will make it that much easier. I noticed the Express has the airtunes and wireless printing, nice but not a selling point. But it also says it's an access point? Why wouldn't I get this over the bigger Extreme base station? All computers in the house are wireless now.
