thanks for all your replies.
i'm not that tech savy to know all the details, ofcourse, but what i meant with running fast, was the system opening the file browser, web browsers - all almost instantly, in windows 7. The first run of programmes in Ubuntu is true, i have the same issue with the applications loading very slowly when i run them for the first time. Example: i have a 4gig ram, 2.1gig dualcore intel processor, 500gb of disk and an integrated graphics card (intel). the laptop was purchased in spring 2010. and i remember windows being painfully slow after time (ofcourse i was so unknowing of the processes i didn't know a thing about fragmentation and registries and stuff), and a friend offered Ubuntu by chance, so i gave it a shot and loved it. After that, i got more into tech. (not that much, but now i know more than an everyday user, who barely knows how to install an office suite, even if it's just clicking next next).
+ should my machine run 12.04 without problems? And windows? (i did check the requirements for both, but it's rarely a help, because i get a whole bunch of different answers).So yeah, basically, i was just wondering if the Win performance will deteriorate over time, or have i just 'done sth right' when installing so it runs great...
+ the thing i like about Ubunut, despite all the philosophical differences, is that it acts pretty much like a total suite, free of charge (and i'm not stingy, i've donated to Debian, Mageia...and used a bunch of different distros over the course of time), no licensing issues (if i run win7, it's ofcourse not going to be a purchased copy), + Libreoffice's integration of docx in 4.0 is better than ever. I have an in-house cloud service (and it works without problems for me) and i like it because i don't need third party software for it. So yes, it's handy-dandy. But as many others, keeping gnome 2 and developing it would be more than a good choice, despite me liking gnome 3 and unity
So yeah, basically i'm at a crossroad, since both seem to be working on a fresh install (i installed them on the same disk, and one at the time. in no moment was dual boot an option).
But also, is it philosophically 'better' to run ubuntu than win7?
Thanks again guys.
