I'm with ya. I picked the 128GB iPad. Love it. After owning all iOS devices to date....we've accumulated a lot of apps that I'd forgotten about. Cool to go through the 'purchased' section and D/L anything I wanted

1080p editing on the Air is a blast (& the files are large, as are iPhone photos and manipulation). vJay and dJay are incredible..and having 5-10,000 songs on your device locally, not relying on the cloud is killer. I've got several magazine subscriptions, one a British Mac rag that weighs in between 6&800mb a month! Games can be as large as 1.5-2GB.
More is better. Price per GB goes down exponentially as you double from 16--32--64.
Sincerely doubt it. I think we may be seeing the bi annual iPod Touch update moving forward. Next year, the A7. Thin, small, long battery life and no more than
64GB. It's the industry maximum of on board NAND right now. Google is trying to get all Android OEM vendors to remove SD storage as it's a joke (I own a Note, a pair of them...as my wife has one too. Can't get out of that contract quick enough). You can't put what you want on the card. Apps, app info....very selective of what is possible to put on the SD card and it's reliability is extremely suspect. Access is slow...I get faster 'media' access (music and video) from my LTE signal half the time than music stored on my SD card.
That said, Apple, Samsung, HTC, Sony, et al are not using SanDisk's weekly Best Buy SD card special or equivalency for on board storage. Look at nice and large Compact Flash storage, you'll get an idea of what efficient, fast and reliable solid storage costs. Next year we will see 128 in the iPhone. It'll be another differentiator or similar to the 2014 flagship releases from the competition
Typically they're subsidized. You pay a portion of your monthly bill so you don't typically drop a thousand up front. Two, three or four hundred. The very cool thing about the iPhone though, it holds its value. While you should never look at a phone as an investment, I've been fortunate enough since the first iteration to recoup my yearly investment plus a 50 or 100 dollar bill. This is pretty uncommon with electronics...but with a wife and son on the plan and every other year upgrade options, we take advantage of them. In the USA, if you don't the carriers aren't required by law to reduce your monthly bill once your subsidized purchase has matured. It's silly to continue paying a bigger carrier like that with an old phone. You don't lose money as the bill is the same
Month to month, mom and pop carriers and specific SIM card retailers may make owning an older device more justifiable...the ability to sell an iPhone for as much or more than you bought it for, use that money to get the latest model....and continuing to pay the same bill. Economic and common sense
See above. They're damn near worthless. As most other 'Droid OEMs have figured out. They're a HUGE PITA!
You've got a '5' in your signature. So you paid $300, right? Why is another 'C' note such a bad deal? $/GB is a significantly better deal than the 32GB model
