The Toshiba e740 (review on the PC Authority Web site) boasted great features such as Type II CF and SD/MMC card slots, and the optional expansion pack which includes a VGA output and USB port, allowing the connection of a keyboard and a projector. The e750 goes two steps further. You can now send 16-bit colour to a projector at a resolution of 800 x 600, and this WiFi version connects wirelessly to a suitably equipped Toshiba projector.
Another WiFi enhancement is support for Voice-over-IP with an enhanced microphone socket so a microphone headset can be used.

Toshiba hasn't made any serious changes to the chassis, unless you count slightly modified front buttons, so all the e740's peripherals work with the e750.

The only notable physical change is the 3.8in trans-reflective screen as opposed to the 3.5in screen in the e740. The extra 0.3in won't make a huge difference in general use, but the new screen's rich colours and bright backlighting shouldn't be ignored.

There are quite a few changes underneath the surface too. The 400MHz PXA250 processor has been 'upgraded' to the 400MHz PXA255, promising performance increases of up to 40 percent but in general use the changes were barely noticeable.

Intel claims the new processor will also extend battery life, but this is only notable if you drop the speed from 400MHz to 200MHz. Unfortunately, it doesn't have the option to change automatically depending on the demands of the current task (unlike Dell's Axim X5 – reviewed on the PCA site). Still, it lasted for more than three hours over three days, and with the ability to charge directly from the PSU plus optional extended life battery, this won't be a problem.

Another bonus is the extra 32MB of flash memory included. This means you should never lose all your vital data. With 64MB of 'normal' RAM included as well, there's a fair amount of storage for additional apps and data.
The e750 WiFi offers a number of excellent improvements on the e740, but it's a shame Toshiba doesn't include the expansion pack as standard – at this price, we expect a little more in the box, and Toshiba should make more of this unique feature. Also, bear in mind HP's iPAQ H5450 (reviewed on the PCA site) costs about $1,499 and includes Bluetooth, WiFi and fingerprint-recognition security. Perhaps more tellingly still, Dell's Axim X5 costs a mere $591.
