| Browser: | BOLT | OM 4.2 |
| Does it force the user to reload pages? | + | - |
| Simultaneous pages kept in RAM memory | - (no in-memory caching at all) | + (depends on size; in general, up to 30) |
| Page loading speed from server | Generally, very good to excellent | Generally, acceptable to excellent; sometimes poor, though |
| Once loaded, speed of positioning to the text | Can be very cumbersome, esp. on low-res, no-touchscreen, slow models like the BB 8800. VGA WinMo touchscreen devices fare far better. | +: generally, it only takes 2-3 quick button presses to quickly zoom into text and position to the text body |
| Favorite synchronization | - | + (Opera Link; can be – manually – synced even with non-Opera desktop browsers) |
| Dynamic zoom in/out from text reading | - | + (in the default, non-One Column mode) |
| Text reflowing | In cases, highly inferior to OM – must use far smaller chars to avoid having to horizontally scroll – even with Mobile View enabled | In general, excellent: works just great in non-one column mode with most sites; if it doesn’t, then, One column helps this. |
| Scrolling: Quick positioning to top/bottom | BlackBerry: + (T/B, respectively); WinMo: - (not even the hardware keyboard works – except for the numeric keys) | + (repeatedly pressing #3 – or simulating it with an assigned hotkey) |
| (Touchscreen devices): Scrollable scrollbar | - | + (they take up quite a lot of screen estate, though) |
| Does it try to keep the horizontal alignment while vertical scrolling (see explanation HERE)? | - | + |
| Real rubberband & inertia on touchscreen devices (see explanation HERE)? | - | - |
| Characters: VGA WinMo devices: maximal charsize (see the reason for this HERE) running under THIS hacked Jbed | It uses its own charset; therefore, much smaller than OM’s | Much bigger than BOLT’s |
| Quality of custom charset: readability vs. (small) size | Better than OM | Slightly worse than BOLT |
| Internationalization support | -: As it uses its own characters, the size settings are more dynamic but no support for non-Western languages at any charsize | +: It relies on the system characters, except for the small charset. No Western support in the latter. |
| WinMo: Emulating / using the keyboard to enter stuff: Entering shortcuts on virtual keyboard (brought up by assigned hotkey) | - (keyboard is minimized at once) | See BOLT – caused by Jbed |
