Why Isn't Google Spidering My Site?

Assuming site linked in sig? If not LoL I spent alot of time on wrong domain... BUT:

site:slow-computer-solution.com : I notice subdomains also, but your www.* seems to have cache-date 10/07/2010, so I think it's getting re-crawled ok.

your subdomains have dates 09/27-29 or so, realistically I think they are fine.

Considering updating your sitemap.xml file, there's some outdated information in current one (current site map reports 25, yours has 23 entries). Make small mods to each page (minor changes should do ok) to change the date modified (but not all at once, spread these micro-changes across 5-7 days). This shows activity and gives SE a reason to re-visit you. A fuller sitemap will include changefreq and priority tags (xml-sitemaps.com will generate this for you).

Also, sitemap generator reports broken links? Try to use a 404-redirect (.htaccess can typically handle this on a linux server) to handle dead pages, eliminate links that point to non-existent 3rd party resources, 404 your own on-page assetts. Re-submit updated sitemap to google WMT after you've done above in about a week and patiently wait.
Also, higher PR sites do get re-crawled more frequently, but you can increase your own crawl rate by consistently having an updated sitemap that reports relatively frequent changes on your own pages.

PR1 on primary domain, I imagine it gets re-crawled ~2-3 weeks, subdomains at PR0 maybe 2-4 weeks for re-crawl/cache. Might be wrong but that's my general experience.
