With June now officially upon us and the financial year almost over, if you've been thinking of purchasing a PC, now is a sensible time. If it's a business machine, you'll be able to deduct at least some of the cost in this financial year -- and with sub-$1,000 machines now common, you might be able to do it in a lump rather than over four years (check with your accountant).
An even more pressing reason to buy now is that manufacturers are officially supposed to stop selling any machines (apart from certain ultra-portables) with XP on them after June 30. If you want a PC that actually has a useful Windows operating system, not the pig-with-lipstick experience of Vista, then you'd best order soon. While there'll be downgrade rights options after that date -- meaning you can purchase a Vista Business machine and ask for XP to be installed instead -- who needs the extra hassle? (We note in passing that July 1 will also see tax rates increase on cars costing more than $57,123; go crazy, motoring freaks!)
