There's nothing really wrong with them, but fans of Windows will be waiting until Windows 10 for phones is finished before they get the flagship Windows Phone they have been clamouring for.

Today, Microsoft launched the Microsoft Lumia 640 and the Lumia 640 XML. Running Windows Phone 8.1 and the Lumia Denim update, the handset will also be fully upgradeable to Windows 10 when it becomes available later this year.

Under the hood, the Lumia 640 is powered by a 1.2 GHz quad-core Qualcomm Snapdragon processor and 1GB of RAM, 2500 mAh battery, 8GB internal memory (with support of up to 128GB with a micro SD card).

Meanwhile, the Lumia 640 XL will have a 3000 mAh battery, capable of giving you up-to 23.7 hours of talk time (on 3G), and up-to 39 days of standby time and a larger (5.7 inch) screen.

A nice bonus when you buy the Lumia 640 / 640 XL is that you get a one-year subscription to Office 365 Personal, which includes potentially unlimited storage on OneDrive and 60 minutes of Skype calling per month to landlines in over 60 countries and mobile phones in eight countries.

The Lumia 640 will begin a global rollout in April, and is expected to be available in Ireland expected to be around EUR 139 for the 3G model and EUR 159 for the LTE model, but the final price may vary depending on the Mobile phone network.

The Lumia 640 XL will be available in single SIM and Smart Dual SIM variants, with a global rollout starting this March. It will be priced at EUR 189 for the 3G models and EUR 219 for the LTE model, before taxes and subsidies.
