I guess the licensing of content means that it no longer makes sense to allow the user to store it to a hard drive. Also, not many people want large boxes where the bulk is mainly the hard drive and the provider would benefit in support costs due to mechanical parts used, SSDs have never been used so I guess they are not cost effective. Even Freeview PVRs have declined in popularity, so those that have got used to apps probably wont miss the recording function much anyway.

You can shove SSDs into Sky+HD boxes, and they will work. They're not optimised for them but they'll work. The supported boxes will take up to 2Tb drives.

I presume in theory you could shove SSDs in other hard drive based PVRs if you really wanted to.

SSDs have come too late really for use in modern PVRs as standard, a 64Gb SSD when the technology first became mainstream and a decent size about a decade ago was something like £90 (I know because I bought one for my computer of the time), Now you can get 2Tb SDDs for not much more than that, though you have to factor in an adaptor as the original drives in Sky+HD are 3.5", whereas SSDs are 2.5".
