I would like to know if there are any current tablets or ereaders that will read manga efficiently. I would like it to have expendable memory or alot of internal memory around 16gb, have a large screen say larger then 8 inches if possible and around or below £260 ($420) and what your viewpoints of them are. I've had a look at the kindle DX, nook color and the archos 101 tablet though I realise the Motorola Xoom and LG slate are coming out soon. The purpose of the tablet is to mainly just read manga though I dont mind extras

. The files can be in picture of pdf format though pictures are easier.
So what would you recommend ?
If you helped it would be a great help =]
