My laptop died, couldn't afford another so bought this - very good reviews on Argos! Had it less than 24 hours, and I HATE it! When I turn it on, it says 'no sim'. - OK, not major, but 'why' when I have wi fi? BUT - I'm a bit of a FB addict, can't play any games on it - not supported! Also very slow in bringing up messages from FB - my old Android phone is quicker! The touch screen doesn't always respond either! I AM pretty computer savvy, but this is threatening my Silver Surfer status! If it were not excluded from retailer's 30 day return, it would be going back ASAP! My two technologically challenged sisters LOVE their tablets - I hate mine already, but am stuck with it :'( Any advice, suggestions, support would be DEEPLY appreciated! Thanks.
