My apologies for getting back to the topic

The two Xperia X currently for sale here made me look into it again. I never liked the X because it seemed so HUGE but I suppose I could live with it, especially at eBay prices which are MUCH cheaper than those asked here on TMO.

But I have not been following the development very closely and find browsing through 254 pages of posts, mostly off-topic or contradicting each other, rather confusing.

So...

Could anyone be so kind as to summarize, BRIEFLY, in a few bullet points, any pros and cons of going X? What works? What does not? Is it worth it at all?
