From what I know, the specs I have seen in different sites have been inconsistent, I am a bit skeptical abt the Datawind, (because of the ordinary site they have), but from what I have checked from different sites, however inconsistent they maybe, I am going to point out the highlight differences between the Aakash 1 and Aakash 2 (ie. UbiSlate 7), the Aakash 1 was available for book last week, and it is already 'sold out' as per their official site, while UbiSlate 7 is in pre-booking stage. They have promised to deliver the product by 1 week as far as Aakash 1 is concerned, and UbiSlate7 only tentative date - end of January is given.
The booking process is pretty straight-forward, they have a form for each Aakash n UbiSlate7, fill the details, you get a Code for further reference, and you get a confirmation mail of the same Code too. Since Aakash is sold-out, you will find only the UbiSlate7 pre-booking form.
May I list out the differences as far as I know:
1. Price: First and basic difference, UbiSlate7 is priced at Rs. 2,999/- while the Aakash 1 is Rs. 2,500/-.
2. OS: Aakash will run on Froyo (Android 2.2), and UbiSlate7 will be Gingerbread (Android 2.3). Won't make much of a difference for a layman apart from that the User Interface will look and feel slightly different.
3. Processor: The major difference which I am was impressed was that of the Processor, Aakash is a modest 366MHz speed ARM 11 chip, and UbiSlate7 is a decent Cortex A8 700MHz processor. To be simply put, better performance.
4. Battery: The battery powering the Aakash is 2100 mAh, and UbiSlate7 is 3200 mAh, again without getting technical, it would directly translate to Aakash ~3hrs backup, and UbiSlate7 ~5hrs backup.
5. Network: Both have a Wi-Fi connectivity, Aakash doesn't support GPRS, while the upgrade UbiSlate7 does. Some sites suggest it might support 3G dongles - but no concrete info about that.
- Phone Calls: You've guessed it right, since UbiSlate7 supports GPRS, it obviously has the sim card and hence supports both Calls and Messaging Service, the unknown is whether or not 3G sim can be used.
6. Production: This is non-technical and unrelevant, but still its a difference, Aakash 1 is a Made-in-India Product, while the UbiSlate7 is produced from China.
There are a few more differences/enhancements believed on the UbiSlate7, but the data is not so consistent as the ones specified before this,
Inconsistent:
RAM: It's believed to be upgraded to 1GB in the UbiSlate7, but I am not convinced if it is upgraded from 256MB to 1GB.
Camera: The Upgraded is supposed to have a front-facing camera, but again it is not confirmed.
That is all as far as differences major n minor or concerned, let's look at the overall specs and features both the product offers:
- Display: 7" Display with a 800x640 Resolution. Follows the same road as most other market Tablets with a screen-size of 7 inches(diagonal)
- Input: Resistive Touch-screen, Resistive supports stylus/objects(can be still be used by fingers also) but is the primitive form as far as Touch-Screens are concerned, Capacitive touch-screens are superior featuring in latest Smartphone/Tablets like iPad etc.
- Memory: 256MB RAM, this is not ideal for these devices, still it is proven to work just fine.
- Storage: 2GB Internal flash memory, 2GB-32GB External Storage - microSD slot provided
- Ports: Two USB2.0 ports are provided, USB devices like PenDrives, USB keyboard can be used
- Weight/Dimensions: The weight is about 350g. Dimensions are Height-7.5"; Width-4.67"; Depth-0.62"(~16mm)
Looks, if you have seen the prototype of the tablet when the idea was proposed, you will be surprised how much the product has evolved from its prototype, it follows the iPad style with a single home button and not the typical 4/5 buttons a typical Android device will feature. Sleek design and the back has a rubber feel to it.
Add-ons:
- USB Keyboard case is provided by the company itself for a supposed price of Rs. 300/-
- Car Charger
- External Charger
