Why did we come down from the trees?
"But for what?"
So that the large vertical bands that ran down my TV screen on the four analogue channels I could pick up well due to large buildings that had gone up in my vicinity 20 years ago, would go away.
And so that I could pick up Channel 5 without all that snow.
And so that I could watch old shows like The Professionals, Sweeney or Minder that would never have been repeated in a million years on analogue TV.
And so that I could watch TV on a huge screen in my living room without the picture looking like I was viewing through the bottom of two Pepsi bottles due to stretching a fuzzy 576-line analogue image across a 50" LCD display.
And so that I have access to a rolling news channel on the occasions I'd like to watch it (such as riots or natural disasters).
And so that I could click one button to record a whole series instead of having to enter the times and dates of every episode of a series into the LCD of a VCR, not helped by the fact it could only store 8 timers and many shows no longer broadcast at a consistent time each week.
And... so many more reasons besides.
Frankly, I'm baffled by your attitude on an techno-savvy website like this. It's not like you're asking what's the point of Twitter or the MS ribbon. You're seriously not seeing any benefits in Freeview (HD, recording or otherwise) over analogue TV!
I bet you're an IT middle manager who gets to decide what equipment to buy for the real staff to use. Staff who'll spend the next three years of their work hours wasting most of it as they try their best to compete against your 21st century rivals with woefully underpowered and not-very-suitable kit running Windows 98 because you think the jury's still out on all this 'NT' stuff.
Raid array? What's wrong with just buying yet another box of external HDs, with each employee name written on them in white marker? if it's important, we'll just burn it to CDR. Simples.
