I hope the rollout of the A1222 is smoother than this. Amigakit and Acube haven't even listed the X5000 yet and GGS Data are the only European dealer that currently list them as being in stock although I believe some of the others had stock and sold it already. I had hoped they were using the time during the delay of the OS4 port to build up inventory at the dealers so everyone could ship from day one. I understand there are probably financial reasons such as dealer not wanting to tie up too much money in stock they had to delay the sale of, or Amigakit not wanting to give credit/too much credit.
Hopefully with the a1222 being a lower cost board/system the 2 problems mentioned above are less of an issue and when they are announced as being available to buy, they really will be available to buy from your preferred dealer.
