in germany, all pop concerts are general admission (if it's a larger venue, there's general admission in the arena and assigned seating on the sides). and i prefer it this way, cause the only difference would be that you have to "fight" (in whatever way, whether it's queuing for ages or getting pushed around or probably both) for a front row place on the day when the tickets start being sold, instead of on the day of the concert. and experience shows that most of the front row seated tickets end up on ebay for astronomical prices.
anyway, that's what i experienced when trying to get tickets for the UK Take That shows 2 years ago... the only possibility i had was trying to get tickets online or via phone. of course i didn't get through by phone, and online i only got tickets in row 20 or so, although i tried the moment the tickets went on sale. then the server crashed, and for the other show i wanted tickets for, i ended up paying 100 pounds for a 2nd row ticket (and that was still cheap!). so in my opinion, the rule for seated venues is: the one who has (and is willing to spend) the money, gets front row.
and actually, i love queuing together with the other fans on the day of the show, cause that is where you meet and get to know people. i just prefer warm and dry summer temperatures.
