Based on a very quick google you've got a point - my "5 years" guessimate is
probably a little quick.

True - but I imagine various "paradigm shift" technologies are being worked
on. But they'll probably be a little further off than my "5 years"

  Any evidence that 2TB

I found an article saying Western Digital are expecting to produce a 3Tb
drive by 2010 and Hitachi a 4Tb by 2011[1].

Based on that a system with ~10Tb of storage doesn't look unreasonable in 5
years. Now if I scale back my ambition slightly and if I've done my sums
correctly you need 15Mb/s to record the entire UK Freeview output[2]. Which
would mean you could record 7days worth on a little under 9Tb. Which is not
the few months worth of HD I was talking about but is enough to create the
paradigm shift in user experience I think. Also it's worth noting that the
expectation is that better compression algorithms will be used to squeeze HD
in to existing bandwidth if it ever comes to Freeview - I believe the BBC HD
trials use H.264.

So I think you're right to question the timescales but I think the "record
everything" device is coming.
