I've been craving for a USB LCD for a while.
They're pretty nice looking, interesting for others to see, and pretty useful for seeing how my laptop is doing in terms of memory and CPU. (My Chrome loves to eat my memory, which is why I'd like to keep an eye on it)
So after a bit of research on eBay and such, I've finally found these two:
http://cgi.ebay.com/2004-LCD-Display-USB-Edition-I-Smartie-module-PC-Case-/250680626277?pt=LH_DefaultDomain_0&hash=item3a5dbacc65#ht_3546wt_1139
http://cgi.ebay.com/20-4-LCD-Display-Board-UART-Based-USB-Edition-III-/230517204964?pt=LH_DefaultDomain_0&hash=item35abe567e4#ht_5576wt_1139
They look the same, eh? They aren't.
On the back, there's a better way of plugging in a ambiance sensor (which is possible to use IF I find one), and there's supposedly a lot more features.
Cheaper one:
More expensive one:
So, which one is the better buy? (I'm looking to see whether I should get the one with more features with a higher price, or the other one with smaller features, lower price.)
