I am using Win 8 at the moment.
I bought it as a present to self and to keep up with advancements.
To be quite frank - I think I prefer Win 7.
I have had this machine for just over a month. Used it every day.
I still have trouble finding my way around.
The vast majority of the apps on the Start Screen I don't use.
I leave them there ...... just in case !
I do like the boot time.
It is quick.
Getting used to the Search Charm - which I quite like too.
Why have they got to call it a "Charms Bar" ??
It sounds like something from Harry Potter !
I know this OS was designed for touch screens - and this, presumably, will feature more in the future.
My son has his own buisness and manufactures and sells interactive LCD screens.
He says that he has to use Win 8 ( customer preference ) but hates it !!
I have not got to that stage yet. :)
