Is a tablet good enough to replace a laptop? My laptop is acting like it is going to die and I do not want to get a tablet if there are things that the tablet can't do. I would not need it to connect to a 4g system but need wifi. Is file storage a problem? I don't know what is all in there but 40GB of my hard drive is now filled. Is there a way to get a program like MS Office onto the tablet? Any limitations?
