If you gave away your old $600 iPad, it would have only cost $1.65 a day to own (assuming you owned it for a year). Sell it for $300 and the ownership cost drops to 82 cents per day or about $25 per month. Heck, I spend way more than that on Starbucks, or my cable bill.
I guess my point is, anyone who feels they're "screwed" because they are going to get $100 less for reselling an iPad, maybe needs to re-evaluate their finances better. Something having cost you $25 per month over the past year should be trivial.
I agree with this. People who bought the first gen iPod have had the best part of 9 months use / pleasure out of these devises. I didn't buy the original iPad but I'll be buying the iPad 2 - 64gb WiFi + 3G version as soon as I can.....
I've never been one for selling electronic stuff. If I upgrade I either keep the old one as a back-up or give it away to a friend or family member.
I've got a load of Nikon 35mm camera gear that cost me thousands but because of the switch to digital is now worth very little.... I'm not bothered though as I've had my fun out of owning and using the gear.
