Long live progress.
It does not make my gadget any worse - so why would I care?
The only instance of new models being released too soon is when the producer stops supporting the old one. SONY and its readers is a case in point. They really have been not-fixing problems with current models (and I mean, not even simple firmware fixes, at times, of obvious problems) while releasing new ones. That's just not right.
But I just bought an iPad3 last spring. I had an iPad1 and I used it until the touchscreen died on me. At that point, I jumped and bought the 3. But I was never tempted to upgrade.
Yet, this year is different. I have lots of PDF files of whole textbooks and it really bugs me at times how slow my iPad 3 is at scrolling through them. I wonder if the new processor would make a difference. If so, I might talk to my IT department and see if I can justify the expense to them
