Eh, that's not true. He, like everyone from Wired to Ars, talks about how awkward it is to use as a tablet that you hold due to 16:9 and 1.5 lbs.
Valid criticism shouldn't be thrown out as a matter of course.
Some of that is valid, sure. Even while using the Win 8 preview, I noticed the same third party app sluggishness often present in windows phone.
I'll have to see if I have any issues holding the device. Isn't it the same weight as an iPad? Same thickness? I know it's longer, but some of the issues may be subjective. For example, the thin edges of the iPad make
it impossible for me to hold it comfortably for any extended amount of time and I don't think I've ever read a single reviewer mention that. I feel like I'm crazy.
Plus the Engadget review seemed generally more fair, I don't think Topolsky is going to give windows a fair shot but we will see. He was also critical of ios6 in his iPhone 5 review but it didn't seem to hurt the score that much.
Edit: just got an update to the Amazon mobile app. The changes? "now compatible with Windows Phone 8". IT BEGINS.
