I'd say the uptick has more to do with people unloading them and trying to get as much as they can while they still can. On the other hand, like you said, it makes for a cheap tablet for someone who wouldn't normally have the chance to purchase one.
I guess I should be a bit more specific with my ebay observation... I'm not referring to the number of auctions for Surface devices but for the number of bids and the aggressiveness of those bids. People who want one watch these auctions and will frequently bid and snipe like few other items I've seen.
In June 2014 I traded my Surface 2 in @ Best Buy ($250) toward the purchase of an 11" MBA. A year later after missing that little, nimble, and quick device I set out to pick up another one. It took me about a month of stalking ebay auctions, throwing in spec bids occasionally. I eventually snagged a mint 32GB S2, black TypeCover, 32GB microSD card, and Incipio padded case for $117.
WillysJeepMan, great commentary. Just as a 10" laptop with MS Office the RT and Surface2 are a great value. I love mine; even if I were to get a newer Surface Pro or 3 my original RT would stay with me. The screen is fantastic and it works well for displaying music. Not sure I'd want to put a $1299 Surface Pro 3 on a mic stand in some dive bar to host my charts for a gig, but a $200 Surface? No problem.
Exactly. The usefulness of the Surface RT/2 has improved for me with the release of LibreOffice 5. I rely heavily on LibreOffice (because of its cross-platform capabilities) but it didn't do a great job handling Office documents produced by Office RT. But with LO5, it handles them nearly perfectly. (close enough to not be bothersome during development and requiring only a few minor tweaks before printing)
I regularly work with documents with complex layouts/formats. They started out in iWork 09 Pages format, I then recreated them by hand from scratch in LibreOffice's .odt format and again in MS Office .docx format. At any given time I may need to edit docs in Pages, LibreOffice, or MS Office formats.
I've been pushing the S2 to see just how much of what I do on my Macbook Air and Acer Aspire Switch 11 can be done on the S2. I'm getting surprisingly far.
I've got some incentive though, I'll be going on a cruise in November (but will still need to do some work during that time) and I want to take only the S2. So far, it's looking good, very good.
