Microsoft Windows 8 Pro ( Upgrade)
Microsoft makes an aggressive, forward-thinking, and bold statement for the future of PCs with Windows 8, and vast security and speed improvements more than justify the $40 upgrade price.
Microsoft Windows 7 Home Premium
Windows 7 is more than what Vista should have been, it's where Microsoft needed to go. How much damage Vista did and whether Windows 7 is enough for people to finally abandon Windows XP are questions that nobody has the answers to right now.
Windows Vista Home Basic
Windows Vista Home Basic is essentially warmed-over Windows XP, Windows XP SP3. If you're currently happy with Windows XP SP2, we see no compelling reason to upgrade. On the other hand, if you need a new computer right now, Windows Vista is stable enough for everyday use.
Microsoft Small Business Server 2003
For small businesses that need a business in a box and want to stick with Microsoft technology, SBS 2003 is the only game in town.
Mac OS X 10.1
Panther adds new and useful features, but at the expense of some old standbys. Current Jaguar users need not apply.

Mac OS X 10.2 Jaguar
Take a good, hard look at Mac OS X 10.2 if you're adding a Mac to a Windows network--Jaguar's new tools can't be beat. But home users, beware the $129 upgrade price if you're not looking for networking options.
Microsoft Windows XP Home Edition
Despite its many annoyances, XP is a worthwhile upgrade. Unless you need corporate administration tools, XP Home Edition should suffice for most--even for small businesses. Enterprise customers, look to Professional Edition.
Microsoft Windows Me
Millennium is a great face-lift for Windows 98, but it's not a necessary upgrade. If you have technical difficulties or work with pictures or music, try the new OS. But if you're happy with Windows 98, stick with it.
Microsoft Windows 2000 Professional
Windows 2000 isn't for the gamer or the casual surfer, but if you have a yen for speed, stability, and some serious server tools, this business-class OS will do you right.
Apple iOS 9
iOS 9 is coming this fall, but we spent some time with the public beta and like what we've seen so far.
