I am planning on purchasing an Acer Aspire R 14 laptop. I specifically researched the R5-471T-52EE model (http://www.pcmag.com/article2/0,2817,2498473,00.asp). On Acer's website I didn't find this particular model, but the following models all have the same specs:
The only difference I found between each of these models is a slightly difference battery capacity.
Can someone help me understand why there are 4 practically identical models of the same laptop, and if there are any significant differences I am missing?
