No reason for those two to be separated for normal users, at all.
Drives Bigger than 2TB. WHEN?

I think they'll hit the maximum storable on a drive before long - they're getting to the limits of what perpendicular storage can manage... pretty soon they'll reach the point where it's simply not possible to place two magnetic charges any closer together.
They can always add a few more platters, but it means that 3.5" is going to be out ahead of 2.5" for the foreseeable future.
IMO SSDs are going to catch up and overtake long before that - look at the current rate of accelleration... it's already hitting 250gb levels, and it's much more expandable than mechanical systems.
Hard drives will still have a use in long-term storage where noise is less of an issue, unless the SSD manufacturers manage to overcome the relatively short maximum lifespan of their products.

Hmm whatever happened to 5.25" HDDs? All cases are big enough for them because of optical drive bays (apart from maybe the occasional HTPC with slot-loading optical drive) and the much greater space available for platters should give an increase in size akin to 3.5" drives vs 2.5" drives, for cheaper (500GB 2.5" laptop - c.£70-80, 1TB 3.5" desktop drive - c.£60-70).
There's probably an obvious reason why, but I'm not seeing it.. only thing I can think of is increased heat/noise maybe?

The random access time would be measured in weeks! It's difficult enough for current 3.5" HDDs to get their heads quickly lined up with the narrow tracks that PMR gives you. A 5.25" HDD is going to have an arm assembly with far more mass and hence momentum to deal with.
The last mass market 5.25" HDD had a seek time of around double that of it's 3.5" competitors. Granted that's down to having a lower spindle speed but any modern attempt would probably do the same to keep power usage and heat down.
I think they may af already reached it, we never get the latest tech straight away.
Would be great if that is the case and they move their research dollars to SSD's, so we could get them in most computers in 2010, would bring a lot of benefits with them.
