Definitely a good point. I hadn't thought of using a full-screen browser or thought of the "reselling" Gmail aspect, although the latter doesn't bug me per se.

Ahh….threading, that is a good feature. I don't really get paying for full-screen, but screen real estate is precious.
Seems like if I wanted push AND threaded, full-screen messaging, I'd do push via the Mail app, and get one of the many full-screen browsers available in the app store. One like: http://itunes.apple.com/app/full-browser/id302757…

That would have its limitations too, but at least I wouldn't be handing my money (albeit little) to developers who are in a way, re-selling Gmail (which was never sold to begin with.)

@Joel

good link, and I also use Google Sync with my iphone mail app. However, the Mail app still doesn't have any kind of threaded messaging display. That's one of the coolest parts of the Gmail experience for me, and it's something that the web app already offers. Unfortunately, the web app is also in Safari and doesn't seem to want to go full-screen on its own, so I've got to rely on these little browser apps like iGmail to make a dedicated, full-screen gmail web app for me.

What am I missing?

Agreed Ben, and that's why the cart is a minor complaint — but it's a whole bunch of small points that killed the experience for me.

from my POV:
-they disappear from the app store for weeks without notice, so people who read the review on site couldn't even check the app out
-they come back and offer the app for free in 2.1, offer push for 2009 for only a week and a half (sillymove, but like you said — only $1)
-latest update comes out, price goes back up to $.99 (just plain inconsistent – doesn't affect me).

-latest update claims to add something to help the end user out "here, hide the shopping cart!" – and this would be for users who have already paid for an in-app purchase and no longer need the cart on-screen, or for users who don't want any in-app purchases and don't want the cart on-screen. Interestingly enough, I belong to both groups. I tried to hide the cart, at which point I received pop-ups on every load up insisting that I buy before I hide. Then I tried to activate my 2009 PUSH subscription so that I could hide the cart, but then found out that the app had forgotten I had any in-app purchases at all.

It's also precisely because this app is so cheap that it's a shame. For my purposes, it was a neat litle way for me to access full screen – nothing more. Like you said — if it was something like your GPS example or the 2Do app (which I use on a regular basis) — sure I'd give a crap and try to wait for a fix and contact the devs. iGmail, on the other hand, was a neat little toy, but this update killed the fun for me.
