Con OS X only
TextMate is for OSX only.
Visual Studio can be quite laggy.
Con Not cross-platform
Visual Studio is only available on Windows, which causes platform lock-in.
Con Takes up a lot of space
Visual Studio can use about 6 GBs which a lot of space to be taken from your computer.
Con Terribly slow development
Keep dreaming about features already provided by alternative products.
Con Non-native window frame
The IDE main window lacks a standard window frame (titlebar/borders). A custom solution is used where the custom titlebar contains numerous application-specific controls. This results in inconsistent UX and can also be problematic when you're using shell replacements or other various window-management software (such as bbLean).
Con Tons of feature bloat
If you're doing simple web frontend dev, then VS is far too arcane and feature bloated for most of your work.
