I see your point about size changes...that would be unfortunate, especially since your panel is cut exactly for the device. I hope it stays the same for you!
On that note...
There is always a tension between innovation and standardization with technology...
I've even seen (on these pages) where folks have 5-7 year old equipment they want upgraded for free from IFly...can you imagine if folks wanted a new "free" car, phone, TV, computer, etc. because there were newer models and changes? Unthinkable!
