Here's a little story about refurbs...
i'm on my 4th 2.5G iPhone
The original one i bought, and its replacement (which was a 5K refurb) both died within 1 month of each other. They would not boot past the apple screen.
So i go to get another replacement, another refurb - iPhone #3. Get it home and realize its got a small line of pixels out at the very bottom, didn't even notice it in the store. ugh! Figure i can suck it up as the Apple Store is on the other side of town, well i made it two and a half weeks until the line of dead pixels turned into two lines and got bigger and bigger. Took the 3rd iPhone in for another replacement this last Tuesday, they gave me another refurb... iPhone #4, but its been great so far.
I don't have an opinion against refurbs. And when you buy a new apple product, it says in the documentation that if service is needed, refurbished parts and/or replacements may be used. So be educated consumers!
But refurbs are great when you buy one, I like to save money.
In fact, half the macs in our house are refurbished and sometimes you get a great bonus with refurb (like how my girlfriend got an iMac full of maxed out ram when all we paid for was 1GB),
Or in this weeks instance, i went ahead and bought the iPhone Applecare seeing as how i've owned it 10 months now and have had SUCH GREAT LUCK with the iPhone. Well they just put it through for expiring in Aug 2010, as its connected to the refurb (aka iPhone #4) serial. So i get roughly 10 free months of... you guessed it.... hardware warranty! That means more replacments if something goes wrong again. Maybe i'll make it to iPhone #10 by August 2010.

I really can't be pissed at Apple, yea its annoying when your phone just stops working. But with every other phone on the market you gotta deal with "insurance" and claims and all that other crap, having to drop another $150 for a junk phone each year, no i don't miss that at all. I just take it to the AppleStore and they give me another one. So at least their warranty/service makes up for hardware issues that do arise. And now, by some stroke of luck, i am covered for another 24 months!
