Windows 7 is actually very, very good. The gap between Windows and OS X is pretty small. Apple will probably step it up with the new version. Windows is and always will be plagued by the fact that it runs on many different hardware platforms while Apple is blessed with a unified hardware platform. That is why there is a stability gap and probably always will be, although things are much better now than they were five years ago.
"Blessed"? Apple made the
conscious choice to control the architecture. Not some mythical entity, of which "blessed" is usually the associated action committed.
I don't see Apple as being a deity either.
Windows 7 is okay, but it still has the same problems that have always plagued it:
1. The Registry (it can be cleaned but not compacted)
2. fragmenting file systems (FAT, NTFS)
3. Slow load time post-login
It's got some cool new problems that XP didn't have either: (I'll pretend Vista doesn't exist...)
1. Copying files to a network share shows disk space on the local machine (where the files are being copied FROM) shrinking and running down to 0. A reboot brings back the disk space, and tolls like Windirstat don't show where the disk space has been eaten up by
2. Power-save on multiple monitor systems: At login or workstation locked screens, the secondary monitor is black. Except the power light is green and the backlight is visibly turned on. (real power saving has the backlight turning off and the monitor's power light turning amber.)
3. Does the OS really need to take up fifteen
gigabytes of hard drive space?
XP needed 1/10th of that. Anyone
competent in the industry will say that fewer files on the HDD means less data to cache, more space available for apps (especially as hard drive performance starts to slow when ~50% of the capacity is used), et cetera... granted, the typical HDD size sold today is between 500~2000GB, but Microsoft always benefited from growing technology while all the competitors bothered to consolidate and keep trimmer code. When Win3.1 was out, it was a hog compared to TOS, AmigaOS, MacOS of the time, etc.
SP1 fixes none of these issues, and is a very sizable download as well (750GB+).
For any developments Windows 7 made (borrowing from Apple and KDE for the new search improvements and GUI), it's the same ham-infested pig, but given a new coating of lipstick.
Oink.
mate. They make the right hardware paired with right software. If Ubuntu would do the same, there could be a good competition for
