you do make a few good points about it but even though they are good points they also will none the less be sacrafices by choosing this device:
1) yes, the rumor has it that it will have a very similiar processor as the droid. Keep in mind though that it good for what you use your droid for now. who knows what will be available 1 year from now. certain apps, games, Android upgrades might require a bigger processor. this is not a big issue now but in most cases people are going to be signing a 2 year contract in order to get it so they need to think long term.
2) the battery issue may be true, not sure. i seem to get more life out of my battery when i am over clocked. I dont know if they have some encorperated into their phones like what setcpu does but if they did, that would be an amaizng phone because it would have control of what the processor is set to.
3) i have heard rumors that motoblur might be able to be shut off but it is not concrete at this point. even if you can shut it off it will still take up memory that is not needed if you do not want motoblur. I think they should have an option to download it off of their site and add it if you like to but it did not come stock. some people may like the ability to switch between the 2 but not everyone. I dont know how that will work with upgrades either because if it comes with motoblur 2.1 i would assume the standard Android also has 2.1 and that you would not be able to upgrade to 2.2 if there is not a 2.2 motoblur.
4) i can't even argue about that one haha. Motorola's devices are built with quality in mind. i mean the droid is made out of metal with a plastic back and accents. When you hold a droid, you know you are holding somthing expensive. with htc phones they are light (some people like that, not saying they are wrong for it) and to me they feel cheap and for the majority they are all plastic except for the HTC Legend (i must say i love the way that thing is build, it solid).
all in all, i think Motorola have great concepts now but the shadow is not for me. Bring on the Droid 2 or the Droid Pro
