I have both .. and yes , you would be please with the Skate as you are with the Blade. I would even say that you feel the 800Mhz instead of 600Mhz ( or even overclock 692 ) of the Blade
There is however a point to keep in mind , and it depends of what you've done on your Blade ... I mean what Rom you've put on it ( as I guess you did not kept the default android 2.1 one )
For my case .. I've resized the partition and then have about +- 290 Mb internally for the apps !! ( great ! )
So , when shifting to the Skate .. ( for which I've not yet found a way to change the partitions ) ... falling back to 162 Mb is a big shock !!!
And even the 4.3" screen is not enough to beat the Blade's enthousiasm ..
I'm still looking for the partitions space and so on .. before really taking the decision to keep the Skate (or to come back to the Blade )
