Market growth / Sales
MS Would make more due to volume selling
1) A SP4 roll up / bug fix /some feature for XP £4.99
2) Selling an XP classic based on (1) with all the STUPID stuff off by default (i.e. Classic shell with minimal animation, no personalised menus/Icon hiding, no auto run, all server and other vulnerable services off by default (no File/Printer sharing by default), new users NOT administrator by default, no startup /welcome screen, log in only, file name endings off, no Active X in Browser / Email. No desktop remote HTML or email remote HTML, remote images or Active X by default etc etc. £19.99 Or £29.00 on a USB stick (able to run from USB)
Of course actually I have no desire to see Apple, MS, IBM, Intel, Oracle, Google, Amazon etc be more dominant or successful. Time for USA dominance to be diminished. Let's have some fresh innovation without the American cultural arrogance.
Yes MS IE, especially 6 was stupid. XP though isn't inherently slow and insecure. Problem is stuff on by default, people being admin, stupid MS IE & Outlook and badly written apps that needed gurus to set them up so non-Admin users could run them.
