Love the name/avatar, "i'm lost," but hope this site helps you find your way quickly
I've used Apple's Airport base stations since they were first introduced, but admit I've often questioned why I'm spending way more to create a wireless network than I need to when I hear of others using non-Apple stuff.
I don't think signal power/range is the reason, at least in my case; I can see numerous non-Apple wireless networks from my Mac - far more than the number of nearby homes - so they obviously crank out the power. My AP BS is set to 50% power and still reliably reaches every Mac I use at home.
To me, the primary reason to buy an Apple BS really echoes the same reason we're willing to spend more for a Mac at all: Usability. The interface and integration of Apple's wireless offerings into my Mac is worth the price because I have no interest in becoming an expert on how wireless networks really work so I can fix the occasional problem. I just want it to work, period. Even with Apple's elegant, simplified AP Utility, there's stuff I could putz with that confuses me and could easily lead me down a path I don't want to go, but it's always allowed me to quickly setup/connect/troubleshoot any wireless issues I've had, saving me who-knows-how-much time, which is worth the expense in my opinion.
Just my two cents, and great question.
