Having read some of the responses here, it seems like I'm being misunderstood a little.

1. It's not my intention to compare the N900 to the iPhone. The iPhone Mail app got compared here because I was trying to make a point that "A simple feature was missed by Apple in version 1, which then later got implemented into newer version of the iPhone OS. How could Nokia not see this? Nokia is making the same mistake in its mail app on the N900. Doesn't Nokia learn from other competitions' mistakes"

2. I don't have any issue with the built-in web browser. I stated the web browser's full-screen / escape from full-screen icon as "an indication" that the user experience does not match the Maps application. The lack of icon standardization is also an indication that the N900 is not a well polished production.

3. I am not asking for a "finished" product as I understand in computing, industry standards (QT, for example) gets newer versions and are always on a path of constant changes and improvements. What I need is a well "polished", well "thought out", well "executed" product from Nokia, and stop selling some garage hack jobs, prototypes, in-house mix-n-match products out the door.

4. I UNDERSTAND that it's a mobile computing device, and use it as such. It's a mobile computing device with GSM, 3/3.5G "communication" (voice, text, MMS, e-mails, Facebook, MSN...etc) capabilities.

5. I don't really care about which / what transitions are used, but the point is WHY on earth when we have the technologies and the means to avoid screen flicker when switching between full-screens, the N900 still does so? I'll answer this, it's because Nokia treats the N900 NOT seriously, uncommitted. My point is NOT to do with "How to I get ride of the flicker", but to do with "WHY is it happening, from a product design view point (not technical (i.e. frame buffer crap) view point)".

6. The points made here (including app manager) really comes down to the N900 "Can" be "better". Why is it not? I know there's a point in time when a product becomes "good enough". But if Nokia thinks the current state of the N900 is "good enough" for them to market this as their top of the line "mobile computer" (quoted from Nokia's site)...then I seriously question Nokia's commitment to the N900, question Nokia's understanding of the mobile computing market, question Nokia's background in understanding user experience, and what a polished product should be like.
