I mostly buy on eBay. I find eBay to be cheaper then Amazon. Especially given when you don't have Crime *cough* I mean Prime and a lot of items on eBay already have free shipping. With eBay you have to be careful at what you sell. Like a broken phone or some other broken electronic. Even if the title and description says "broken," some dumb ass will still buy it thinking it works, open a case against you and leave negative feedback. Electronics in particular can be iffy. I sold a TrackIR5 which was fully working. I barely used it. Dude buys it and about two weeks latter sends me an eBay message saying something like, "was this broke?" I was so god damn pissed. He opened a case and I stated it was working when I owned it, etc, but the moron never did send a response so the time frame for him to leave a response in the case expired and I won the case. Complete idiot.
Now PayPal offers a 6 month money back guarantee. So moron can still get their money back withen that time frame. And I used to think 45 days was bad.
As to the death of the PC. I agree about how asinine it is to type on a phone or tablet. Copy & paste can be a PITA too. And no Fing way I'm editing PHP code, etc on a damn tablet. I like my Notepad++ thank you very much. I also fly in FSX with my yoke and pedals. No tablet is going to change that immersion. Especially in the virtual reality realm. 90% of every member or lurker that has come to my site's use a smart device of one form or another and I just find that to be nuts.
This is a hell of a lot better than a stupid asinine tablet. Plan on updating the monitor one day.
