I have owned and used a number of e-ink devices and they are ideal for what they are designed for, reading black and white text. However I have also recently taken delivery of the Archos 9 tablet and installed windows 7 ultra (why on earth it shipped with 7 starter
) and it serves very well as a reader for the photography books that I read which really need colour display to get the most out of. It will replace a lap top for many tasks but will not replace my Kindle. Having said that I have read a couple of novels on it using the mobipocket reader and it has been more than acceptable. With the back light turned down very low I have not experienced any eye strain at all.
I am still experimenting with the handwriting conversion capabilities of the device but it is looking like it will be very useful for when uni resumes in March.
