Any beta testers? How long does an installation of Lion take?
For myself SL takes about 30-40 minutes on a 2009 laptop.
The updates take less than that.
The time machine restoration takes almost a day - lots of media.
How much time does Lion add to the process? I can't imagine it being an extra half an hour.
I swear the people making a big deal about this are a bunch of concern trolls or the biggest whiners I've ever seen. Who expects replacing a hard drive to be no time at all? No one unless it is an install with no prior data ported over.
And how often do you do expect to do this?
Usually when I go through this it is because I'm upgrading to a larger drive and the benefit of the larger drive outweighs the loss of one day use of my computer.
On a C2D iMac it was ~20 minutes. I didn't time it, but it felt like ~20 minutes.
