Hi Tom,
Hi 
I don't think the QuickStarter is made for Gnu&Linux systems. We get a bit spoiled. If things don't almost instantly then we tend to be a bit impatient.
With Windows people get used to their systems slowing down quite a lot or being given a system that is desperately slow. It gets so slow that a number of work-arounds have been built, such as keeping programs open all the time even if they are not being used. This makes them appear to 'open' faster and gives the illusion that the system is more responsive. Of course that tends to slow Windows even more because programs can't share libraries and other components in Ram and Swap/Virtual-memory. So, people figure out work-arounds such as going off to make a cuppa tea or deal with filing or double-clicking a load of times in frustration.
The question is whether you really need quickstarter? Roughly how long does it take to open LibreOffice? It usually is quite slow, like the Gimp. Are other programs also slow? Is it possible to add some more Ram or get a newer cpu with more L1 or L2 cache? Obviously DDR ram is too expensive and just not worth it but DDR2 is cheaper and DDR3 is worth buying at the moment. Cpu can have more impact for less money though.

Quite frankly, I didn't use QuickStarter when it was available for Linux, I preferred to reserve my RAM for other purposes. I usually kept my OOo or LibreOffice open all the time -- I used it for my teaching plans, lessons etc. I normally have FF, TBird, LibreOffice open. I am also spoiled in that I also have 2X19inch monitors which makes it easy to slide windows from one side to the other.
Cheers,
Marc
