You are not completely right. Sony PRS-650 is newer device than EE but for example PRS-600 is older (and it has not many differences). Ipad came to sell about 1 month after EE.
Anyways, I don't want to buy Apple devices. I prefer Android, that's why I have EE. Maybe 2.2 Froyo will change something when it's brought in.

... you know, when you see tablet weighting 2,7 times less than EE with multi-touch ... it's just ENTERTAINMENT to use such thing, it's so enjoyable! EE screen is not sensitive, lacks multi-touch and I find it... let's say not great in the year 2010
