The state of Java support is:

- OpenJDK with Hotspot Zero (default): works fine, but there's not JIT so it's somewhat slow; I've found the performance of tomcat + webapps reasonable (after the first compile of JSP pages)

- OpenJDK with CACAO vm (java -cacao): mostly ok, but has big problem with JMX (as in "crashes the application"); on the other hand cacao vm has a JIT, which means that when it works it's much much faster than hotspot zero (tomcat startup time is reduced to about 1/3)

- Sun EJRE: extremely fast and feature complete. However it's *not free*; you have to pay royalties when deploying the system; furthemore the JRE is still in "early access" phase, it will expire after 90 days.

Reliable and optimized JVM:

Guys, while this is an interesting conversation, allow me to provide a perspective that differs from the dominant one here. I am a manager and a statistician. I would like to run a top-notch PIM suite like Datebk5 from Pimlico Software, just as I ran it when on the Palm. If I can't do that, I'd like to run Agendus or Pocket Informant (in that order), as I can on both Blackberry and Windows Mobile. (I currently use WM and Pocket Informant.) Datebk5 will be available on Android fairly soon. Obviously, the iPhone tends to get most everything.

I could live with an N900 that did not do push email (and it does not, last time I checked), but an N900 that does not have a really top-notch PIM is something I could not live with. The Palm had, when I last checked, a mediocre native PIM and WM currently has an atrocious one. But that's why there was demand for software to provide these capabilities.

If you want to know something about the high-end market, you will find some of that market among people like me who are former Palm users and who want efficient, intelligent design.

The maemo concept and the N900 are magnificent. However, until you guys can implement some of the key functionality available 8 years ago on the Palm, I could never take the risk. Specifically, I would need a top-notch PIM, a really competent turn-by-turn travel mapping program that would reroute if a stop was missed, an app that would give me subway routing (e.g. Metro), and a text editor & spreadsheet that would not corrupt the MS files (OO does indeed corrupt them, at least OO on Linux, but Documents to Go does NOT corrupt them). I would want as well a database program like HanDBase and ideally a List Manger program, though HanDBase could be used to create one. I would need a secure "wallet" program and a top-notch travel program (I mourn for my old Travel Tracker, which has now been ported to the iPhone). ALL of this functionality was available 8 years ago on the Palm. I personally got this functionality on a Palm T3 and used BT to get wireless access from either a GSM phone or from a Verizon phone after hacking it. The functionality is also now available on both BB and WM platforms, and on the iPhone.

I get the impression that such usage has never crossed the minds in the N900 group. Note that while most iPhone users do not use all these apps, they are available for the iPhone because they are ESSENTIAL for some of us.

Thanks guys. I don't mean to be loud here, but there really does seem to be a disconnect.

P.S.: It looks like I'll be moving to the Storm2 from a two-year-old WM device. iPhone is out of the question because of AT&T's really crummy service.
