I'm lucky enough to have early access to one of the XPS13 ultrabooks running Ubuntu 12.04. Here is a quick summary of my initial impressions:
Yep, I've been moving away from Eclipse since it is both a CPU/Memory hog, and also horrible at allowing profiles to be shared over multiple machines. So, I've installed IntelliJ and find it to be absolutely enjoyable. The XPS13 has super fast disk, enough memory, and enough CPU to load reasonably complex projects much faster than did Eclipse.
I have not yet spent any real amount of time using the XPS13 with a remote monitor, so I can tell you that the real-estate is limited.
What's the advantage(s) to IntelliJ over Eclipse? I think the Eclipse interface is a little chunky but otherwise find it to be pleasant.
I don't know if there are advantages really. As someone that is coming from a Visual Studio background learning Android programming for example, Eclipse + a new language was a bit much to handle at the same time. I had several issues with performance of new installs of Eclipe (program hangs and such) that quite honestly could have been caused by my lack of experience. In any case, I am pretty comfortable with IntelliJ now and sometimes its nice to bring something familiar with us to a new environment.
Thanks for your thoughts. I have not yet received one of the ultrabooks, but look forward to it!
I currently use a Lenovo t420 as my secondary development machine, and even with 6GB I find I sometimes wish it had 8. Typically I'm running at least 1 virtual machine, often 2, and memory is typically my 1st hardware bottleneck.
I'm happy to hear it boots so fast! By Lenovo takes 12-15 seconds to get to the password running 12.04.
