Seems to me that
rcodi is perfectly right in saying that an internal microSD card is as friendly as it gets, in the context of this thread (which is, maintainability of an ereader in time). When the internal memory fails the external microSD slot isn't going to be of much use, right? Not to mention that OP is talking about modding an used device, whose warranty I would imagine to be expired.
Either way, this is a very interesting project
I own a Glo HD (a used one, but one of those Christmas presents that never got opened, so I was quite lucky!) and I totally agree with you that if one wants to buy a Kobo at this moment and have it last, the Glo HD is the perfect choice. It has current e-reader specs and it's ridiculously easy to open and substitute both the internal microSD and the battery. In my case, I've already done both: the first to upgrade to a faster memory, and the second because the original battery started failing and giving me problems a few weeks ago. I got the CameronSino battery as well and so far it's been working splendidly, and I can attest that the installation was very noob-friendly, as it's got the same connector of the original one -- no need to solder anything, just attached it, fixed the battery in place with a couple of pieces of double-sided tape, and that was it. Not very fancy, but I'm looking forward to some tips from you!
