No reading...Need New Glasses!

OK, my glasses are only 4 - 5 years old...but I need a new prescription for my line-less bifocals.  It makes book reading almost impossible, if not merely annoying!  Here is where an eBook would be nice, since the type size could be easily enlarged!  I've looked at several and the "Nook Color" is my favourite, but at $250 still kind of pricey.  The WEB surfing and virtual keyboard aspect is excellent.  Perhaps now that the iPad2 is out, they will lower the price?
