Hello, and thank you all for the replies
Indeed I once had the screen of my PRS-505 replaced for some damage, and have since then used a homemade protection made of a book/Bible cover, some sheets of plastic foam and hard plastic (result is hard protection + zipped up- alas, 40 euros a bookarmor is a bit too costly, IMHO- shipping this side of the pond is a huge con factor*).
It's quite interesting richman's remark that after all, the screen is just
one part that can be broken in some kind of accident. I hadn't considered it... so I guess the best solution would be a replica of the PRS-505 case. I can be wrong, though
Cheers, and thank you again! (and in advance to any poster willing to carry on the thread- there are a lot of solutions!)
* in all, the cover costed me a bit more than 10 euros, and it has survived a handbag not always well-handed in the car AND some pressure in being sandwiched with a netbook into a messenger bag during a train journey *crossfinger*
