I actually like the Lume Pad although I often feel blocked at every turn when trying to use it for various things.
The Lume Pad’s biggest weakness isn’t actually the weak hardware: the specs are actually pretty OK if you aren’t trying to do crazy stuff like emulate the Nintendo 3DS. I paid $300 for mine and that made me suspect that Leia is selling it at a loss. I’d have been OK with paying a little more to get a few more features.
No, the biggest problem with the Lume Pad is the lack of a micro SD card slot. (and exFAT support on the software side to go with it) The whole device feels really crippled without this. Try to store any 3D movies at all (ripped from your 3D blu rays) on the device and you’ll quickly run out of space. Try to use an external micro SD card reader to carry more with you and you’ll run into the stupid FAT32 file size limit of 4GB per file, forcing you to split your movies into 3.99 GB chunks, or compress them to hell.
Yes, I know you can stream over wifi and I have been using that, but that’s no good for car trips. For me, discovering that I can’t really store my 3D movies on the device and watch them without the Internet was a serious, “You had one job” moment for the Lume Pad that I was/am pretty mad about.
The fact that the Lume Pad was merely following a larger industry trend of taking away the micro SD card from flagship Android devices is no excuse because there is no excuse for that blatantly anti-consumer industry trend. I start seeing red whenever I think about whoever made that decision, starting with Apple. At least it still had the audio jack.
It is advisable to never store any files you want to keep on the Lume Pad because if their software screws up (as all software from all companies eventually does) then there is no way to recover your data on this device. That, by itself, justifies the need for micro SD cards in Android devices, so that you can just pop the card out and there’s all your data. Besides, they’re dirt cheap and getting cheaper and better all the time!
For a slightly different topic, here’s the second biggest weakness: One other thing the Red Hydrogen One and Lume Pad generation of devices didn’t have that I’d have liked to get from Leia would have been some way for fully open source apps to provide 3D content in a vendor-neutral way, similar to what Facebook has done with OpenXR. Anyone who knows me knows that I’m a passionate hater of Facebook but even I couldn’t complain when they retired their proprietary Oculus APIs in favor of OpenXR. I’d want the vendor-neutral API to include a way to run stereoscopic 3D apps like those made for the Lume Pad on VR devices as well. The same APKs. The app shouldn’t be able to even tell if it’s on a real Lume Pad or if it’s on a virtual 3D screen in VR or AR because the API should be the same. Developers want to write their code once and have it just work across all devices forever, not spend God only knows how long tweaking it for every quirk of every proprietary platform. It should just work.
(later edit) Third biggest weakness: Seems like you should be able to use the Lume Pad as a 3D monitor for your gaming PC (running SBS 3D gaming content with VorpX or SuperDepth3D or other similar apps) but I’m not aware of that being possible. Please let me know if anyone has figured out a way to do that. Obviously, gaming has a low tolerance for latency.
