Let's count the challenges shall we?
1) If you happen to click the link for Version 2.0 in the Chrome browser running on an iPad it gives you a blank screen.
2) If you happen to click on the link in the Safari browser it gives you the download page but the App store says "This App is no longer available"
3) If you read the announcement all you see are iPhone screen shots, which makes me wonder if "iPad support" consists of a "2X" in the corner of the screen like it does on the Google Voice app. Gee, That lets me use 16 pixels on my retina display to show one pixel in your App, I'm so thrilled.
Ok that last bit was a pretty snarky, the snark comes from my massive disappointment at how unbelievably bad Google has been at dealing with the existence of tablets. Have you tried to use Google Docs on a tablet? Gmail? Reader? Every product they own has the "mobile" version which assumes you can hit every button with your thumb, or the "desktop" version which assumes you've got a keyboard and 5 button mouse under your fingers. Hello, its been years.
Here is hoping that when they actually put Gmail 2.0 back into the App store it is useful on iPads. I've got $10 - $20 for the right email client for the iPad, anyone want that money?
