Since day one

[pinosilano]

I'll propose at your attention this pretty strange phrase, at least for me, founded in an informatic forum:
I have an older Dell Inspiron 5100 that's been rock solid since day one.
I understand that the fellow tells:
"Tengo un viejo laptop sólido como una roca hasta que un día.":o
How can I translate correctly this phrase?
Why is it written back to front?
Thanks.

Since day one means from the very beginning; from the first day. I'm no expert, but i guess it should be something like desde el primer día.

Why is it written back-to-front?I agree with 'desde el primer día' as a possible translation, and add 'desde el principio'.

Thanks Rusty for all the corrections to my english. If you and every one always do it I'll be very glad. :dancingman:
