I previously had a 2DS. I had been reluctant to get into handheld gaming, but Club Nintendo from my WiiU purchases provided me with DKC 3d and NSMB2. Then I got smash fever and scored the 2ds for $80 on a pre-black friday deal.
Recently got a N3DS XL for $175 and had no trouble transferring my 2DS data to the N3DS. This process deleted data off my 2DS after it transferred, but was able to redownload all my previous eShop purchases with no difficulty. That said, people who tell you that your eShop/Nintendo content is locked to the hardware are being deceptive. That's only true to the extent that your eShop content only exists on one 3DS at a time. So in my case, I didn't need to repurchase anything.
Had planned to sell the 2DS for $ to fund the N3DS purchase, but managed to get a trade from a buddy at work for Kid Icarus : Uprising, Castlevania : Mirror of Fate, and Kingdom Hearts 3D.
Though 2DS was serviceable for gaming while traveling, 2DS to N3DS was a very, very worthwhile upgrade. More comfortable and better suited for adult, home use. Recently picked up ALBW too and it's one of the best Zelda's I've played!
I really appreciate the extra speed/power it has over 2DS/regular 3DS along with the improved 3D. There's a large backlog of 3DS games I've yet to try as well (Super Mario 3D Land, Fire Emblem, MK7, Pokemon OR/AS and X/Y). While these all could have been fun on the 2DS, I really feel I'm getting way more out these games with the N3DS.
I predict NX launches in 2017 - not 2016
