Can rocks and boulders not be compared to each other?
Actually one might want a rock for one thing, or a boulder for another. You need to decide which is more appropriate for your use.
Not so much compares as much as weighing the pros and cons of each and how it affects your use. While the Treo 750 is clearly inferior in terms of the specs, it's conveniences could completely outweigh the benefits of the 8925. But it depends on what's important to you.
I grappled with the decision between the 8525 and Treo 750. While fan boys will state that there is no comparison, that the Treo sucks and the 8252 is clearly superior, I have to say I disagree on some levels.
The way I use my PDA/phone on the go, I find it difficult to deal with the 8525 and the slider keyboard. For text messaging alone the 8525 was a bit inconvenient.
When weighing the benefits of the 8525, none of it mattered enough to not make me want the conveniences of the Treo 750.
Now the 8925. Clearly a (boulder) leap forward in generation of features. Now that scale has shifted. I can no longer ignore the benefits of the HTC super PDA.
Can I forgo the things I love about the Treo design. Now that I've become very proficient with using all of the treo exclusive features, can I give them up?
We'll see. I've decided I can probably do without the Treo "stuff" just so I can have the sheer power and glory of the 8925. I'm getting the Tilt and hopefully won't look back (much.)
