Glo What's up with the bad contrast ratio?

I like the design, the form factor and the uniform lighting but what's up with the bad contrast ratio?

Sony PRS-T2, 13:1
Bookeen HD Frontlight, 11.5:1
Kindle Paperwhite, 11.5:1
Kobo Glo, 10:1... same as the +3 year old Kindle DX.

I think I will cancel my Kobo Glo backorder (my first e-reader) and do some more research before buying.
