It's kinda weird to use your personal account to ask this (instead of an anonymous one). Based on your submissions here on HN (https://news.ycombinator.com/submitted?id=_evnr) and a quick google search for your name (which throws up [links redacted]), it becomes obvious that you are talking about [name redacted] and saying that it is not going anywhere.
As for your questions, do what's best for you. It's also usually best to leave out emotions when making these kind of decisions.
It doesn't matter if it's been 2 years or 2 months, as long as you have a valid reason for quitting, you shouldn't be stereotyped as an "unstable" employee (even more so, if you are good at what you do).
I'm in Mumbai as well, so if you need to "talk" to someone before your decide, I'll be more than happy to lend a ear.
Have been using the 2nd gen Dell XPS 13 developer edition that comes pre-installed with Ubuntu and I'm loving it. Wasn't all smooth sailing though: http://www.sandeep.io/157
The latest edition is even better.
At the time I also looked at the ultrabook from System 76 but decided to skip it because of keyboard issue reports and lack of support in my country.
Edit 1: The keyboard on the Dell XPS is nowhere as good as a Thinkpad, but it beats them on form factor, price and support (at least in my country).
Edit 2: The X1 carbon has a slightly flexible carbon-fiber chassis which I didn't like but it's a great option if you want a bigger display than the XPS 13 and don't mind the price.
Thanks. The launcher icon of the current version appears smaller on the Nexus 4. Will be fixing this soon. BTW, I upgraded to Nexus 4 from the Nexus One about 3 weeks ago :)
Why do people direct comments at AC assuming he will read them here? Isn't that a little self-centered? Wouldn't it be more appropriate to leave such comments at the original post?
