preferred it over the 760/860. In March 2005 the C3000 product was joined by the SL-C1000 which returned to the traditional 128 MB flash memory but lost the internal micro-drive. The C1000 was cheaper, lighter, faster in execution due to running from flash memory, but would require the user to "waste" the SD or CF card slots to fit a memory card for mass storage; at the time the largest card supported was 1GB. The C1000 cannot be upgraded to fit an internal micro-drive because vital components were missing, but the space can be used to fit internal Bluetooth and Wi-Fi modules using the USB host facility. In June 2005, Sharp released the SL-C3100, which had flash capacity of the C1000 yet also had the micro-drive, and proved a very popular model indeed. The 1000, 3000 and 3100 models were overclockable, boosting the device's ability to play back video more smoothly. In March 2006 the latest model launched, predictably labelled as the SL-C3200. It is basically an SL-C3100 but with the newer 6 GB Hitachi micro-drive and another tweak to the case colours. The Intel PXA270 CPU is a later variant, and some would regard as inferior because it cannot be overclocked so highly. The kernel gained a vital tweak to the Sharp proprietary SD/MMC module and allowed 4GB SD cards to be used (and this was quickly borrowed by 3000 and 3100 owners). The software package gained text-to-speech software from Nuance Communications and an upgraded dictionary. While the SL series devices have long been sold only in Japan, there are companies in Japan who specialise in exporting them worldwide; sometimes without modifying them at all, sometimes an English conversion is available at extra cost. Not all Zaurus models came from Sharp with universal (100/110/240 V) power supplies (the Zaurus takes a regulated 5 V/1 A supply), so either an additional or an exchanged power adaptor would be needed, and not all exporters provide this by default. When buying directly from an exporter in Japan, the buyer is liable for import duties and taxes, and attempting to avoid them can be a criminal offense. There are also companies in the US, UK and DE who are unofficial resellers; one notable example is Trisoft who prepare and certify the device to "CE" standard compliance. Since there is no official export channel from Japan, Sharp offers no warranty or repair service outside
