My new computer came with Microsoft's latest operating system Vista.
When the machine first arrived it would stall for about 10 - 20 seconds every few minutes or so. Not the sort of thing you expect on a new computer. Fortunately there was a simple solution to be found on Dell's website which cured that. The problem apparently only occurs with Vista and lies with the Intel chipset.
There were a few programs that I used on my XP machine which won't work with Vista. Some had updates available others I just had to ignore. I also had to abandon my scanner and web camera which were too old to have Vista drivers written for them.
The computer loads up a lot faster than my previous machine and runs a lot faster but then so it should -it has a dual core processor, 2Gb of RAM and the hard drives are in a Raid 0 array. The aero interface is a lot less boring than XP's - more like Apple's OS 10.
It is hard to say whether the machine would have been as quick running XP and I certainly don't intend to reformat the drives to test it out!
So if you are considering upgrading or a new machine - Vista is obviously going to be the future system. Be aware though that not everything will works as you expect it.
Now my next challenge is how to record the footage from my video camera on to the hard drive.
