Airwolf, every forum has people like you, basically you can't afford the latest stuff (or are happy with a certain standard), and go around trying to slate the newest one to feel better about what you got.
You told us all you did tests, but you posted none of those tests so we could see your level of expertise and the results, a lot of the people posting X5 videos are not good enough to get the most out of it, you only have to see some videos from a few people to see in the right hands, its better.
The bottom line is, this is an image related business, if you're too complacent or too poor to accept that better is better, then that's fine, but stop trying to rip into people with a better attitude towards their work. Cos I'll just come back over you and say my shits better than yours.

Yes it costs me.
Yes its not as big as I would like.
But its still better and will be noticeable, especially when I start using it in lower light conditions to get shots I would not even bothered trying to get with the X3.
You know you want the X5 really, you're just trying to tell yourself and others you don't so you can escape that nigging feeling.
Superior optics, megapixels, sensor size, cleaner video, better 3d models, better for marketing purposes, if you still choose to rubbish those inconvenient truths then that's your choice.
And someone with an S900/GH$ can PROBABLY say the same towards X5 owners.
And someone with an S900, and GH4R can PROBABLY say the same towards them.
And someone with.......
My point is, this is an evolutionary business, Some people buy iphoneS models, others only buy the source models. This is no doubt an S model, but its still better
