Note that I am not discussing the relative merits of SSDs and HDDs, just the hard realities at this point in time. I spent more than €100 on a 20 GB SLC drive because I also think that a good SSD is the best investment for a new computer; but they will not be a true replacement until prices are comparable. Just as when LCD monitors cost over €1000 (or $1000, prices are equivalent), they were not a replacement for CRTs but an expensive luxury.
I see nothing in your links that contradicts what I am saying. The first article acknowledges that SSD prices are about $1/GB, while HDDs are $0.05~0.10/GB -- about 10~20 times lower. The second link states that HDDs will not recover until next year, hardly the time frames we are talking about.
A low end laptop is about €500, and a cheap 500 GB SDD is bound to cost almost that much. Until a comparable SSD costs about 10% of the laptop price it will not be a replacement -- people will just have an external HDD for bulk data. As to the high end, you can redefine it to be "laptop with SSD", but if you look around you will see plenty of €1000+ models with an HDD -- starting with the lower MacBook Pro. There are also many models with a 128 GB SSD, but at 1/4th the capacity they are hardly a replacement.
We are just not there yet, sadly. A breakthrough may come and shorten the time frame, but I don't think that TLCs are it: they will just lower the reliability and may give the whole SSD category a bad name. Not even high-temperature NAND annealing will help as it is (from your first link) at least 10 years off. Perhaps we can agree on a time frame of about a decade until HDDs become a rarity.
