First of all, you need to decide if you want the new reader to access your old ebooks or if you're only terested in compatibility for future purchases.

Then you need to determine which format your Sony readers are using. If they are in DRM'ed LRF format there is no way that I know of to get them onto kindle. You choice then becomes to accept that those books are only readable on the Sony reader or to buy another Sony reader as nothing but Sony supports DRM'ed LRF format. (That *was* the intent behind the design, after all.)

If they are in Adobe ADEPT-DRM'ed ePub, you will need to learn to strip the DRM and then run the ebooks through Calibre to convert them into Kindle format. If you are unwilling to do this, the effect is the same as if they were in DRM'ed LRF: you need to buy only readers that support Adobe DRM. That means pretty much anything *but* Kindle.

If you don't care about your existing books (and since you said the reader sees little use they may not be many) and you are willing to learn to DeDRM books (it is not hard, really) you can then buy from Amazon and convert to ePub or buy ePub and convert to Amazon-compatible mobipocket format.

Otherwise the dueling DRM schemes will mean you will have books only readable on the Sony and books only readable on Kindle.

It all comes down to dueling DRM's and you are caught in the crossfire; either learn to strip it and convert or learn to live with incompatible readers.

Sorry, but *that* is the reason DRM is generally reviled. It brings nothing but grief.
Just a clarification. I believe that LRF formatted books with DRM are LRX format books (i.e. if it's .LRX it's DRM infested, if it's .LRF it's not). I'm sure somebody will correct me if I'm wrong on that. Also, if you have purchased LRX books from Sony, you can now download for free the ePub version of these books direct fron Sony (with DRM, I presume).
