If access is only used for storage (no UI), I would suggest you opt for SQLite instead, my experience with it shows better performance and 100% open-source (used in applications holding up to a few hundred thousand records and complex queries). You can also find JDBC drivers for it and I think...
As I said before, the Java Runtime Environment isn't something continually running in the background (not a service or a daemon), if you kill the java.exe (or javaw.exe) it won't be running anymore. If the problem persists, then the problem isn't with the JVM it's with the application itself and...
More often than not I tend to find that more RAM is better than more CPU for Office tools; many people have many opened applications that use RAM, but usually have only one "active" at a time (unless you run lots of background jobs like music/video processing).
Very (and I mean very) few devices have HDMI inputs (except switched and stuff like that), I think I've only ever seen two, one was a kind of Tuner and the other is the Logitech Revue. I've never seen a laptop with HDMI in, not even high-end ones.
My guess is that if it has 2 DIMM slots, it will support 8GB just fine. Sometimes it's just that they didn't bother qualifying the device with that much so they simply put 4GB as the limit. The other thing is that if it ships with a 32 bit OS, saying it supports 8GB might have been interpreted...
I would recommend against OCing a netbook; those things already have very little ventilation and can run rather hot at stock (I wouldn't want my C-50 netbook on my lap during heavy CPU usage).
I can try a few things tomorrow, I'm by no mean a Perl developer. I think it's more of a very advanced scripting language than a programming language anyway (more a judgement of what the language should be used for than the quality).
As for Perl coming from C#, you got it backward as Perl is...
BTW, I don't know how flexible it is, but if you want to try prototyping your UI in Windows, you might want to take a look at Rainmeter. This small article was published on LifeHacker about it today.
