Anyone know what's the difference between Herotab M802/APAD IMX515 & FS-805T A8. When I look at the spec they look identical to me. I find that FS-805T is US$50 cheaper than the Herotab (including shipping) but without a leathercase. I am thinking to get the FS-805T and wondering if I could get a leather case that fit it? Many thanks!
