I just sold my 650/BC last night on eBay, for 3 reasons.
1.) It is worth too much for me to own if the 950 is fetching not much more.
2.) I feel as guilty as having a $230 device that only reads books as much as I love this technology.
3.) I realized I really want a 950 instead. For me as an engineer I'd like to carry all the datasheets I have on one device instead of printing them. And it being a larger device with extended PDF viewability, it may be the best option. Just wished it came in navy blue like the 505 or black like the 650.
So I hate not having a reader, but feel guilty about owning something so expensive and uni-purposed. Would I make another mistake by buying a 950? Kind of wished I scored one for $225 like that other guy too
