FCC filings show iPad Wi-Fi + 3G is larger


In addition to the disclosure in Apple’s just-published FCC filings for the iPad that there are two Wi-Fi antennas per model, a separate Apple document has disclosed a previously unknown difference in the dimensions of the Wi-Fi and Wi-Fi + 3G models. According to the document, the Wi-Fi + 3G model is 0.3mm taller and 0.1mm wider than the Wi-Fi only model, in part apparently due to the 3G model’s top antenna panel. This is in addition to a previously disclosed 0.1 pound difference in weight between the models, which was announced on the date of the iPad’s introduction in January. Though this difference in dimensions is very modest, it will likely impact the compatibility of individual iPad models with some precision-molded cases and other accessories, which are commonly manufactured to fit tightly on Apple’s devices.

.3 mm and .1mm?
That’s pretty negligible.

Is that worthy of an article?

Yeah, it is, because developers and users both read this site, and are probably going to want to know that this previously undisclosed fact will impact whether their iPad cases fit both models.

I hope Waterfield’s all over this as I’ve pre-ordered both a case and a sleeve from them!

.1mm is the thickness of a piece of copier paper.

.3mm is the thickness of a typical business card.

These “differences” from the non-3G model are, as a previous poster said, negligible, and insignificant for a product of this size.

#4: I’ve had conversations with iPhone and iPod case developers whose entire products are .8mm or 1.0mm thick and use laser measures to determine proper manufacturing tolerances for their products. Your judgment as to what is “negligible” or “insignificant” really isn’t especially relevant unless you’re actually making, selling, or using these products, particularly the ones (as noted above) that are precision form-fit rather than just sleeves with give in each dimension. Even then, Apple’s the company that specs its products to the tenth of a millimeter rather than the millimeter, and similarly gives developers access to highly detailed dimensional drawings for a reason - it wants things to fit, and fit right. Tiny differences have caused problems with past accessories.

0.1mm is less than the change in length that results from warming up from room temperature.  I.e., negligible.

Good lord.  It’s a point of interest.  If YOU’RE not interested, please move on.
You guys are making a$$e$ of yourselves here.

#7: Yeah, it’s always amazing to me that people actually waste their time posting “I don’t care or get this” comments. Move on is the nicest possible way to put the thought that comes to mind.
