i was looking for ways to expand the memory of my k2. I'm still thinking about it because my eyesight is such that eink is the only way I'd ever be able to back to college.
i have my cellphone on it's lowest brightness setting that seems to work great!
i bought a droid 3 cause i REALLY loved it! well, the kindle for droid works great, and the droid 3, yeah i know old as it is, has a good sized screen and ALL my kindle books & a boatload of books in other formats. it can go webside, it can play music & movies. it can go wifi or 3G. now if only the kindle for droid would let me have a black background with green text? I'd be in heaven!
my D3 has 16 gb memory inside plus a 16 gb micro sd card. that's 32 gb overall...more or less. when i can afford a 32 gb card I'll see bout putting that in. so problem temp. solved.
i still plan to look around and maybe doctor my kindle a bit for the tech manuals when i do get back in school. that's why i bought the K2 to begin with.
just thought I'd toss my 2 cents in as well.
cheers everyone!
