My sister got an ipad 2, she's now wanting to sell it and has already bought a laptop to replace the ipad, which she thought was a laptop replacement

My mother is also wanting a laptop again and doesn't use her tablet a lot any more

I did tell them it's not a replacement for laptops

Pages on the ipad is a mediocre word processor at best, and won't give you all the compatibility that MS Word would, typing on any touch screen is a pita for me as I touch type, not hen peck. Typing a lot would require a B/T keyboard imo, pretty much making having a touch screen device for word processing pointless, this is assuming the OP does a lot of word processing as it seems to be a concern for him.
