Sony E-Reader PRST1

Now that Sony doesn't have their store anymore, if I buy a sony ereader T1, will the adobe reader still be able to be downloaded so that I can read my books?  I have a Sony 950 but after 7 years I think it is crashing and burning so I'm thinking of buying a new Sony ereader....partly because it has the ability to have external memory But if I can use the reader program anymore, then it will be a waste of money.  Please help!
