发帖数: 15010 | 21 Why buy such ele. dictionary? It does not worth it!!
I bought one a while ago. After I bought my smart phone for $120, I never
use my ele. dictionary again. Actually I tossed it in garbage can 3 days ago.
My smart phone has several dictionaries. I used one all time with
pronunciations. Such smart phone offer you much more, I mean much much more
functions and funs for about $100 than a ele. dictionary which I paid for $
70. All these ele. dictionary should be out of market now. |
