As the time time passes, everything develops and so does the technology. The 2k14 tabs are way to back to compare them in terms of features, speed or design. This tab has a big screen but compared to now any tab will be better than this.
Its features are 512 mb ram, where as any tab will give you min of 1024 mb ram at that price range. Its camera quality is very low 2.0 megapixel back and 0.3 megapixel front. In any newly releases tab you will get better camera than this. Resolution is very low . Display colour is 133 ppi which also very low compared to now which gives 216 ppi. Its supports only 3g no 4g.
I think that these are some minimum basic features other than battery backup, you will need to know while buying a new tab.
