I'm confused, really. And yes I've searched it, I'm here after reading tons of "reviews" out there plus quite a few threads in here, all to no end. Because nothing seems adequately answered my simple question, can Maemo-powered mobile computer good enough as a push mail device? I get it that Modest is broken and currently no alternative solution/work-around is sufficiently compensate for it, but how broken is really it? Like many people, I'm using several mail accounts with gmail serves as Mail for Exchange push central. Connectivity varies between wifi, 3G or EDGE but data always on. Someone clicked send, seconds after I'll get some forms of notification (sound, vibration or both). Two or three touches away and I'll be looking at my new mails residing in their appropriate boxes. Replies are handled seamlessly with also appropriate accounts. That's it. My past mail experience with Symbian, Android or dare I say it , Windows Moblie and Iphone, more or less managed to be just like that. I wonder which part of said above description will stay the same with Maemo 5, I mean N900. I hear some said it takes forever to open the mail app, lost connect with mail box...etc but can I fix it by leaving Modesty always running with acceptable memory/performance loss? And what's about Ovi mail service? Can I replicate my smooth experience by replacing gmail with ovi mail (of course I prefer not)?
And please no more sick joke about login and reading in X-term. As much as I love those nice, clean command line screens over GUIs , for a mobile mail client it's simply not feasible, ever. This is the only question before I take the plunge and ditch Iphone for good and buying N900 to be my only device. Thank you all.

P/S : I want to say this community is really incredible, to the point I'm not hesitate a bit about future support knowing Maemo is officially dead.
