Unless someone manages the impossible and replaces the CPU with something else (even going to a dual core would be helpful, I really wish this was something that could be done, oh well) we're basically stuck with using PCI-E devices to squeeze more life out of these now five year old machines that were underpowered at the start of their lifespans.
Getting a Broadcom 70015 decoder card seems like a good move given it alleviates headachs when browsing video.
Ditto with looking at other Wifi cards as A/C and 5ghz become more widespread. One of these cards seemed to even include bluetooth which is likely a newer version than what the board itself supports.
I have heard that installing a new SSD would also bring performance gains, but I don't know what sort of gains can be expected, and what I'd read is 2011 era so now a few years old on its own.
I just haven't seen a list of things that look like they'd be useful.
While yes you can use your phone/tablet as a bluetooth remote, I'm more a dedicated remote sorta guy (buttons!)
Tutorials on re-packing the battery with fresh cells?
Any good drop in screen replacements? Replacement Trackpads, keyboards? Can I just source those from spares intended for newer chromebooks and drop them in?
Apologies to the group, but the hardware is getting long in the tooth and I don't want to let it go because it relaly is a nice feeling bit of kit.
