Are microSD cards free? No? Then they add to the cost, so saying something is irrelevant there is a lie. To equal my 920's storage will cost an additional $20 or so, and that's to have slower storage, which is a negative anyway. Oh, and saying that most people use more than 32 GB of storage is total guesswork with no evidence to back it up. I use the storage of my phone more than anyone I know, and I've got several GB clear on my 920. Most people probably don't crack 10 GB of storage. Not everyone has a deep music library and offline maps.
By the way, I only mentioned the 822 because that's what my sister had. It was the same thing as the 820, except with a different body and more internal storage. The 820 is LTE- and HSPA+-capable.

Sorry I don't like light-colored devices, I find them hideous, so the aluminum is a big turn-off. Stating aesthetics as fact is the reason I officially consider any further comments you make to be worth less than nothing, because you are trying to say I am incapable of having a different aesthetic preference than you.
The 8x0 devices are VERY similar. There are a bunch of little improvements, but the core of the 830 is worse than the 820 (due to carrying a junk GPU), meaning that as a whole, they aren't all that different, in terms of my perception of their overall quality. Of course, someone who is really big on optics will think differently (and if that person is able, he'll go with the 1020 instead), but on the whole, there isn't much to say about the 830 over the 820, while the 920 is a clear winner, to me.
