Think Secret is reiterating a report published by AppleInsider in March stating that Apple intends to stop manufacturing and sales of the 17-inch iMac.
The site also notes that a refreshed iMac is on track to arrive in late June but will only feature 20 and 24-inch models.
Think Secret is also reporting that Apple could switch from using a 23-inch display to using a 24-inch Display in its Cinema Display HD line-up. The move will apparently come "very soon".
