Query: Microsoft should recall this keyboard

I am returning this keyboard.Product:Microsoft natural ergonomic keyboard 4000 - advanced ergonomic designModel:1048Reasons:1. It is not ergonomic design by any means2. spacebar is hard to press when you actually type .3. your fingers/wrist might experience pain if you use this; It happened to me.you wont understand what i say if you simply try this keyboard in stores. you actually need to type a document using this and u will know why the keys make it hard to type. it is amount of pressure needed to type a key is different when u press them individually vs while typing a document when all fingers are in use.-Don't know which ergonomic evaluator approved such wiered keyboard.I would give it ZERO stars if I could.Suggestsions for Microsoft:1. split the space bar into two buttons to atleast make this keyboard usable.2. reduce finger pressure required to press all keys specifically spacebar.3. increase the size of enter button. and reduce size of most keys.
