I should hasten to add, Win10 will go out in waves, mostly so servers have some hope of coping w/ demand. The 1st to begin receiving it are the Insiders, And Reserves, of course. The caveat here is not everyone, everywhere, or retail shelves or OEMs... it will not be ALL, straight-way as of 29/7/15. Yes, that is the official Launch date for the Windows 10 GA BUT, it is not being rolled out to everything, everywhere simultaneously on the 29th. It begins on the 29th.
HP & Dell claim they will offer Win10 units on the 29th. We'll see as RTM only went out this past week..
Yes, believe heard can be (pre)ordered, now, from a couple of online sources.
