no dramas, can't help it if someone wants to embarrass themselves really heh.
just to fortify my statement if I only work in 44.1khz 16bit quality on a low end windows xp $400-$500 desktop pc with cubase + zoom r16 etc with my experience and ears which I take very well care of as compared to a full fledge studio with 24bit 48khz/88.2khz/96khz/or even 192khz with killer latencies counts and high end preamps etc but a case of "gear better than user" and engineer is also a musician who jams and performs without earplugs eventually resulting hearing damage.So a case of a good result mix which I assume is what you're trying to achieve is general hands on practise on your mixing (eq/compression/reverbs) , your recording (mike techniques etc) , a good budget gauge which you realistically can justify your spending on so you don't splurge what is considered overkill.
2 more factors you'll need to take note
1a) desktop minuses will be bulky , non portable, may even be noisy due to the fan if you're recording vocals near it. takes up more power for electric bills i guess. desktop pluses will be the interferences from hard disk writing is lesser (that digital Transformers kinda sound), better individual part warranty if you're buying DIY (my usual shop is
www.fuwell.com.sg) if you're getting self proprietary brands, avoid acer. asus is good. better upgradability (2gb ram / 4gb ram or addon more hard disks) . mainboards with firewire will buspower your audio interface that has bus power support. depends on what audio interface you get. remember for hard disk get one that spins 7200rpm , don't go "green". it doesn't destroy the ozone as much as if you were to crank a 5400rpm speed hard disk.
1b) laptop minuses is (I don't know if it's the same for most laptops) the hard disk writing sound interferences may get into your recording. maybe some grounding problems once in a while. not as powerful as desktop to cost ratio. usually 1 year warranty. (one part down all down problem) , limited hard disk space but easily can get one usb drive I guess. no buspower for firewire.
pluses is the portability/slick layout (if your room is small) definitely. hard disk speeds 5400rpm only.remember to avoid acer. asus is better.
2) 32bit operating system can support up to 4gb ram but compatibility with drivers is safe, 64bit operating system can support up to 8gb onwards but there's still cases of incompatibility. I'd recommend staying with 4gb32bit.
so to answer your question yes stronger laptops can be an option. I recall seeing like a quad core asus laptop at $1K a few months back. just remember to maintain your laptop well and don't install unnecessary trash.
if you're gonna travel often then I do recommend a higher powered laptop.
remember to read the DIY recording FAQ and plan your purchase well with audio interface/mics/cables etc.
