i bought my ipad 3 refurb 3 weeks back, had a problem with it, and got it exchanged 2 weeks ago. but i think i want to replace it with a 4th gen. i am outside the return 14 day period but have spoken to apple who have said i can return it for a full refund and buy the ipad 4. Unsure what to do..the ipad 3 does seem slower on wifi compared to my ipad 2...Is it worth making it future proof as i cannot see me ever buying an ipad again unless it breaks. i do like speed but i dont video edit or do hardcore gaming on it! Is the speed noticeable on the ipad 4 compared to 3. on wifi and general usage or should i keep the ipad 3 and the £130 i have saved.
