$100? What have you bought thats $100? What did I buy that cost $100? Just how the who, when, how, and why did you pull this random number out of your ass? <--- Because that's a realistic difference in price between a cheap MP3 player and an Android phone that doesn't suck monkey balls.
Mini-android-based tablets can be found as low as $37 free shipping if you spend enough time on a chinese site. <--- And they are terrible chinese sh*t and nobody should ever buy them or suggest buying them.
You can go to any walmart. best buy. or family dollar right now and pickup some $50 samsung phone with android and bluetooth. <--- Good luck finding a new Android-powered phone for $50 that's not on contract.
I spent $42 on a used HTC Evo 3D (That one with the 3D screen and cameras) a month ago, Dual-core 1GB Ram, a phone that 2 years ago, would have retailed for more than 10x that price, and sell on eBay for 3x that price. <--- Used being the keyword, also you were pretty lucky with that price. As you said yourself, they sell for three times the price on eBay so in the real world, unless someone is extremely lucky, she/he'd have to spend $126 on the metaphorical Android phone you suggested getting, at least one that's not terrible. That's hardly a small difference in price.
But yeah, I'm going to admit my ignorance that I don't know WTF Tesco even is. $5 mp3 player? Please... Who honestly would even consider that? My knowledge of off-brand $5 mp3 players might pale in comparison to yours, but thats only because anything less than a Sanza isn't even a blip on my radar. And for the price of a Sanza, maybe a little more, at the right time and place can get you ALOT more. <--- Anyone who just wants to play his music without buying a very dear device or anyone who doesn't want this future dear device to get damaged.
So go ahead and stretch the "any brand" quote so out of context of the thread it was posted in to jump off the subject of the Sanza and onto your random toy you found at a store, but I still don't know whose ass you pulled that $5 and $100 comparison out of. <--- You said you don't settle for cheap trinkets. A $60 Android phone or tablet when bought new is a cheap chinese trinket. With that in mind, I assumed that "at least $100" would be appropriate, and that gives us a $95 difference in price.
