It seems the new Windows 7 will start popping up on computers in late October. So if you are thinking of buying a computer with Vista – don’t. Wait until October. Stores and retail outlets have been pushing the 64-bit Vista and the same will no doubt be true of Windows 7 (frequently referred to as “Vista as it should have been”).
Aside from hardware and configuration issues (count on 4GB of member and a dedicated memory card with at least 256Mb of memory), the key issue will be 64-bit machines. However, you need to watch out for this, because many older and legal-specific programs may not run on a 64-bit system. In addition, many older peripherals (printers, scanners, etc.) may not have 64-bit drivers and therefore may not work. Manufacturers have, of course, resisted writing 64-bit drivers: why write a new driver when they can sell you a new printer? So buying a new computer may also entail buying new printers, scanners, and other peripherals as well. Be sure to check this out so you have a true picture of what the upgrade will cost you if you go 64-bit.
True, you can run Windows XP on top of Windows 7 to run your older programs, but this will take a lot more setup. So all in all, going to Windows 7 will be a lot more complicated than just buying a new PC.
At the same time Microsoft has been trumpeting Office 2010, which will supposedly have a web-based version that will work with any browser and on a MAC as well as windows. The kicker here is that apparently (as of now, at least), this will work only if you are running Sharepoint on a Windows server. So again, a lot more complicated than the announcements would make it seem. As with all things Microsoft, buyer beware!
