bought one!
Was in Apple retail shop today, umm and ahh, Wife said "just get it" - different when they are umm and ahh about clothes!!
What swung it is the flash, camera and video for me. The screen looks brighter I have to say and more refined but not as big a WOW as I though it might, but only used it for a little today, busy setting it up etc. ALso It may be a little faster in use, but again, nothing as lightening as I thouht. I did get big pauses on my 3GS with camera app, and settings, these seem to open straight away on my iP4.
What I have to do is to make sure I sell my 3GS for £300, thats how I convinced the wife, ie "it'll only cost me £200 really, and I'll get it back next June/July when iP5 comes out!" - hopefully
thanks people, any last hints? any apps, gotta have for retina display/speed etc?
